Best ResponseYou've already chosen the best response.0Alright, so lets pick up where we left off. Can you find two points on the line?

Best ResponseYou've already chosen the best response.0Yup, that's one, good job.

Best ResponseYou've already chosen the best response.0@ilovenyc Can you find another one?

Best ResponseYou've already chosen the best response.0@ilovenyc Well, go over to 2 on the x axis, and then go up until you hit the line. What y are you at? That's how you get a point.

Best ResponseYou've already chosen the best response.0@ilovenyc Not quite, although the drawing isn't too great. (2,1) is on the line.

Best ResponseYou've already chosen the best response.0Do you see how that works?

Best ResponseYou've already chosen the best response.0Great! So now, do you remember how to find the slope?

Best ResponseYou've already chosen the best response.0To find the slope m of the line segment joining the points, use the slope formula

srossd

Best ResponseYou've already chosen the best response.0Right, so try doing that with (2,1) and (4,7)

Best ResponseYou've already chosen the best response.0@ilovenyc Making any progress, or do you need some help?

Best ResponseYou've already chosen the best response.0need some help do i add those both together?

Best ResponseYou've already chosen the best response.0Not quite, it's more of a subtraction. Here's the slope formula: \[\frac{y_2y_1}{x_2x_1} \; \; \; x_1 = 2 \; \; \; x_2 = 4 \; \; \; y_1=1 \; \; \; y_2=7 \]

Best ResponseYou've already chosen the best response.0@ilovenyc So see if you can use that to find the slope. I'll be back in just a little bit.

Best ResponseYou've already chosen the best response.0@srossd so i need to subtract that

srossd

Best ResponseYou've already chosen the best response.0@ilovenyc Just use that formula I wrote, plug in the numbers. And now I'll be back in a little bit :).

Best ResponseYou've already chosen the best response.0No, here's another hint: \[\frac{71}{42}\]

Best ResponseYou've already chosen the best response.0And ok, now I'm actually leaving for a little bit.

Best ResponseYou've already chosen the best response.0Just a few minutes, though.

Best ResponseYou've already chosen the best response.0@ilovenyc Alright, I'm back now. So did you get the slope from that?

srossd
 one year ago
Best ResponseYou've already chosen the best response.0So the slope ends up being 3.

Best ResponseYou've already chosen the best response.0@ilovenyc So now you know that the line will be y=3x+b. So plug in x = 0 to that, and you'll be y=b. So look at the graph, and go to the point where x=0. Find what y is.

Best ResponseYou've already chosen the best response.0The drawing is bad again, it's actually 5. But close enough that I'm pretty sure you get it.

srossd

Best ResponseYou've already chosen the best response.0So if your equation was y=3x+b, and b=5, what's your final equation?

srossd
 one year ago
Best ResponseYou've already chosen the best response.0No, no  just plug in the value of b (5) to y=3x+b. The x and y should stay.

Best ResponseYou've already chosen the best response.0@ilovenyc Do you understand, or do you need some help?

srossd
 one year ago
Best ResponseYou've already chosen the best response.0Ok, so you solved for b, so just put it where b was. The equation comes out to be y=3x5.

srossd
 one year ago
Best ResponseYou've already chosen the best response.0Do you see how that works, plugging in 5 for b?

srossd
 one year ago
Best ResponseYou've already chosen the best response.0Actually, it's A, since everything above the line is shaded. B would be the opposite shading.

Best ResponseYou've already chosen the best response.0And again, sorry for elongating this so much  I just wanted to make sure you understand how to do it.

Best ResponseYou've already chosen the best response.0@ilovenyc So do you feel like you have a good grasp on how to do this type of problem now?

Best ResponseYou've already chosen the best response.0@srossd i think so...

srossd

Best ResponseYou've already chosen the best response.0Alright, good. I can make up another one for you to try if you want.

Best ResponseYou've already chosen the best response.0well i have more problems that i need to do on my homework

srossd

Best ResponseYou've already chosen the best response.0Oh, ok. Need help with those?

srossd

Best ResponseYou've already chosen the best response.0Ok, want to post a new problem?

Best ResponseYou've already chosen the best response.0@ilovenyc I'll be on the lookout for a new post.
