Answer:
d. y = 4x
Step-by-step explanation:
We will use a slope-intercept equation to represent this. These equations are of the form
y = mx + b, where m is the slope and b is the y-intercept.
We can see in the graph that the line crosses the y-axis at 0; this makes 0 the y-intercept.
To find the slope, we find the rise and the run. The line rises 4 and runs 1 between points; this makes the slope 4/1 = 4.
This gives us the equation
y = 4x + 0, or y = 4x.
