Answer:

Explanation:
Point-slope form:
where a given point is
and the slope is

1) Find the slope of the line (m)
Slope =
where the given points are
and

Plug in the points (-7,1) and (-3,9)

Therefore, the slope of the line is 2. Plug 2 into the equation as m:

2) Plug one of the given points into the equation
We plan either plug in (-7,1) or (-3,9) and it would work either way. Below you can see the equation plugging in the point (-7,1):
