Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - point
We have the slope m = 2 and the point (-7, 5) → x₁ = -7, y₁ = 5.
Substitute:

Convert to the slope-intercept form (y = mx + b):
<em>use distributive property</em>
<em>add 5 to both sides</em>
