Best ResponseYou've already chosen the best response.2Do you know the slopeintercept form of the equation of a line? \(y = mx + b\)

Best ResponseYou've already chosen the best response.0yes i recognize that

Best ResponseYou've already chosen the best response.2That is above the figure you provided. The b part is where the line crosses the yaxis. That is called the yintercept. Look in the given graph. At what point on the yaxis does the line cross the yaxis?

Best ResponseYou've already chosen the best response.2Great. We no have that b = 110, and we have this much: \(y = mx + 110\) Now we need to find m, the slope.

Best ResponseYou've already chosen the best response.2To find the slope, you can use two points of the line. Pick two points that are easy to read on your graph. That means, pick two points that are on intersections of the grid lines. Can you read two points?

Best ResponseYou've already chosen the best response.2One point can be the one that includes y = 110.

Best ResponseYou've already chosen the best response.2Close. It's (0, 110). Since it's on the yaxis, the xcoordinate is 0. (0, 110) is a good point. Now we need another one.

Best ResponseYou've already chosen the best response.0see i was going to say 0 but i thought it wouldn't count since 0 is the orgin

Best ResponseYou've already chosen the best response.0but it makes since since (0,110) = 110

Best ResponseYou've already chosen the best response.0also i just realized that 10,110 is not on the line anyway , lal

Best ResponseYou've already chosen the best response.2You get to the point we are talking about, (0, 110), by starting at the origin. You go 0 right or left. That is why the xcoordinate is 0. Then you go 110 up. That makes the ycoordinate 110. The point is (0, 110) That means start at the origin, go 0 right or left (you're still at the origin), then go up 110. You end up at the point 110 on the yaxis.

Best ResponseYou've already chosen the best response.2Yes, (10, 90) is a good point because it's easy to read since it falls on the grid lines. Another easy point would be (20, 70). Ok, let's use (0, 110) and (10, 90)

Best ResponseYou've already chosen the best response.2We need to find the slope of the line that has those two points. The way to find the slope is subtract the two ycoordinates. Then subtract the two xcoordinates. Divide the first difference by the second difference.

Best ResponseYou've already chosen the best response.2The order does not matter, as long as you do both subtractions int he same order.

Best ResponseYou've already chosen the best response.2You subtract the y's and you subtract the x's. Then you divide one subtraction by the other one.

mathstudent55

Best ResponseYou've already chosen the best response.2Yes. The slope is 2. That goes in the m of the slopeintercept equation.

Best ResponseYou've already chosen the best response.2Notice that if we used the points in the other order, the slope would still be the same:

Best ResponseYou've already chosen the best response.0OK i would just like to say thank you very much for your time here, you have helped me far beyond me expectations, there for, i shall fan you in hope that i may be able to ask for your assistance again c;

Best ResponseYou've already chosen the best response.2When you use two points to find the slope, it makes no difference which point you use first and which point you use second for the y and xcoordinate subtractions. The important thing is to do both subtractions in the same order.
