Best ResponseYou've already chosen the best response.1Parallel lines have the same slope, First, you need to find the slope of the given line, then use that slope for the new line. To find the slope of the given line, solve x + 15 = 5y for y. Then put it in slopeintercept form, which is y = mx + b. m is the slope. Second, the equation of a line with slope m that passes through point (x1, y1) is y  y1 = m(x  x1) Try it, and ask for help if you need it.

Best ResponseYou've already chosen the best response.1Thanks,I need help putting x=15=5y into slope intercept form

Best ResponseYou've already chosen the best response.1First, switch the sides, so you start with 5y on the left side.

Best ResponseYou've already chosen the best response.1Next, the only thing happening to the y is that it is being multiplied by 5. How do you undo a multiplication?

Best ResponseYou've already chosen the best response.0\[x+15 = 5y\]Divide both sides by 5 to give\[\frac{x}{5} 3 = y\]Now switch the sides.

Best ResponseYou've already chosen the best response.1Umm I think that by dividing?? So will that mean that I'm dividing 15 by 5y??

Best ResponseYou've already chosen the best response.1Correct, divide both sides by 5

Best ResponseYou've already chosen the best response.1So then what will happen next to the x??

Best ResponseYou've already chosen the best response.15y = x + 15 Divide 5y by 5 Divide x by 5 Divide 15 by 5

Best ResponseYou've already chosen the best response.1OK I got 53=y ..?..?..?

Best ResponseYou've already chosen the best response.1wait wait! I checked it and it actually its suppose to be y=1/53

Best ResponseYou've already chosen the best response.15y/(5) = x/(5) + 15/(5) y = (1/5)x  3

Best ResponseYou've already chosen the best response.1Remember to include the x on the right side.

Best ResponseYou've already chosen the best response.1Since the original equation is now written in slopeintercept form, y = mx + b, you can read the slope directly. It's the number multiplying x, which is m. m = ?

Best ResponseYou've already chosen the best response.1m=4 so then that will mean that the final answer will be y=1/5x+4 xD

Best ResponseYou've already chosen the best response.1Where did you get a 4 from y = (1/5)x  3?

mathstudent55

Best ResponseYou've already chosen the best response.1Remember, the slopeintercept form is y = mx + b, where m, the number multiplying x, is the slope.

Best ResponseYou've already chosen the best response.1What is m, the slope?

mathstudent55

Best ResponseYou've already chosen the best response.1Correct. Now you know the given line has a slope of 1/5. The line that is parallel to it also has that slope becasue parallel lines have equal slopes. Now we start on the second part of this problem. What is the equation of the line that has slope 1/5 and passes through (0, 4)?

Best ResponseYou've already chosen the best response.14=1/5(0)+b which will then turn into 4=0+b

Best ResponseYou've already chosen the best response.1In the slopeintercept form of the equation of a line, y = mx + b, m = slope (you already know this) b = the yintercept Correct. b = 4, since the point you were given, (0, 4) is on the yaxis, so that is the yintercept.

Best ResponseYou've already chosen the best response.1Then I will do inverse operation and subtract 0 from both sides making it be 4=b

mathstudent55

Best ResponseYou've already chosen the best response.1Now you know your new equation has m = 1/5 and b = 4. All you need to do is write y = mx + b and replace m with 1/5 and b with 4
