Answer:
D. y = 3x + 2
Step-by-step explanation:
y = mx + b,
where m = slope = rise/run,
and b = y-intercept
From the graph we see that b = 2, s we have
y = mx + 2
Now we look for the slope. Start at (0, 2), the y-intercept, go up 3, a rise of 3, and right 1, a run of 1 to the next point on a grid line intersection.
m = slope = rise/run = 3/1 = 3
Now we have
y = 3x + 2
Answer: D. y = 3x + 2
