Answer:
Explanation:
To solve this problem, let's use slope-intercept format as out template. The equation for slope-intercept format is as follows:
mx + b = y
You can find the y intercept by looking at the graph and finding where the blue line crosses the y axis. This happens at the point (0, -1) or y = -1.
-1 is your y intercept [b]
Now, to find your slope, use the slope equation: y₂-y₁/ x₂-x₁
Pick two points on the line: (-2,1) and (2,-3)
Now, plug into the slope equation and solve:
=
= -1
-1 is your slope [m]
Now that you have both slope and y intercept, plug into the slope-intercept equation:
-x -1 =y is the equation of the blue line
