Answer:
D
Explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (1, 7) ← 2 points on the line
m =
=
=
= 2
use either of the 2 points on the line
using (- 2, 1 ) , then
y - 1 = 2(x - (- 2) ) , that is
y - 1 = 2(x + 2) ← equation in point- slope form
