Answer:

C. y = -3x + 1

Step-by-step explanation:

y = mx + b

The y-intercept is 1, so b = 1 and we have

y = mx + 1

Now we use two points to find the slope.

Look at points (0, 1) and (-1, 4).

m = slope = (difference in y)/(difference in x)

m = (4 - 1)/(-1 - 0) = 3/(-1) = -3

y = -3x + 1

Answer: y = -3x + 1

Answer:

C.
