Question

Write the equation of the line that passes through the points (5,—9) and (-7, 7).

Put your answer in fully simplified point-slope form, unless it is a vertical or
horizontal line.

Answer 1

`y-7=-(4)/(3)(x+7)`

Explanation:

The slope of the line is
`(-9-7)/(5-(-7))=-(4)/(3)`.

The equation of the line passing through the point
`(x_1, y_1)` and slope
`m` is
`y-y_1=m(x-x_1)`, so the equation is
`y-7=-(4)/(3)(x+7)`.
