Question

Find the equation of the line that passes through the following points. Write the equation in​ slope-intercept form. ​(-4​,-8​) and ​(-8​,-9​) what does y=

Answer 1

Let's start with the x coordinates.

-8 is on the left, and -4 to the right, so that will help organize this.

the line goes from -8,-9 to -4,-8. it moved 4 over the x axis and rose 1 over the y axis.

rise/run so 1/4 is the slope.

y=(1/4)x - 7
