Question

What is the equation of the line that passes through the points (-5, 9) and (8,-9)

Answer 1

Y+9=6(X-8)

Explanation:

The equation for a line is (Y-Y₁)=M(X-X₁)

X and Y are one set of points.

M is the slope.

To find the slope, take the change in y and divide it by the change in x.

`(9-(-9))/((-5)+8)` This comes out to
`(18)/(3)\\` or 6.

Pick a set of points. I'm going to choose (8,-9).

Y+9=6(X-8)
