Aline goes through the point (5,-7) and has a slope of m= -3. i need to know how to find the y value explain the steps of work i have to follow because my teacher does not accept homework without work

Well, don't you already have the t value ,-7.

(5,-7) m= -3

It's ironic that we're learning the same thing.

First you will need to put the information into point-slope form [y-y1=m(x-x1)]

1. y is y and y1 is the y-value in the ordered pair. m is the slope. x is x and x1 is the x-value in the ordered pair.

y-(-7)=-3(x-5)

2. Solve

y+7=-3x+15
-7 -7

y=-3x+8

3. Now it is in slope-intercept form.

4. The y-intercept is 8 on the graph and y=-3x+8
