Answer:
B.
Step-by-step explanation:
First, using two points (0, -4) and (3, 5), find slope:
Slope, m = 3
Next, determine the y-intercept, b.
The y-intercept is the value of y when x = 0. It is the point where the line intercepts the y-axis.
From the graph given, y-intercept, b, is -4.
Substitute b = -4 and m = 3 into .
The equation would be:
