Question

Write the equation of the line that passes through the points (-9, -3) and (-7,7).

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

Answer 1

y - 7 = 5(x + 7).

Explanation:

The slope m (7--3)/ (-7- -9)

= 10 / 2 = 5.

y - y1 = m(x - x1)

Using the point (-7, 7):

y - 7 = 5(x + 7).
