Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The formula of a slope:
We have the points from the graph (-5, 2) and (5, -1).
Substitute:
We have the equation in form:
Put the coordinates of the point (5, -1) to the equation:
<em>add 3/2 to both sides</em>
