Question

​ HURRRRYYYYYYY PLEASE Write the equation of the line that passes through the points (-8,-1) and (5,−7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Answer 1

y + 8 = 2x + 2

Explanation:

Use the points given to find the slope. Divide the difference in y-values by the difference in x-values.

(-1) - (-7) = 6

5 - (-8) = 3

6/3 = 2

The slope is 2.

Now, pick one of the points to put in point-slope form. It doesn't matter which. You will get the right answer either way. I will use (-1, -8).

y - y₁ = m(x - x₁)

y - (-8) = 2(x - (-1))

y + 8 = 2(x + 1)

y + 8 = 2x + 2
