Answer:

D

Step-by-step explanation:

Remember y=mx+b, where m=slope and b=y-intercept.

-1 is the y-intercept, so the line must cross at (0,-1).

  • This rules out choices a and b.

+3 is the slope, so the line must have a rise of 3 and a run of 1, and it must be a positive slope, which goes to the right like this: /

  • This rules out choice c

So the answer is d.

Answer:

D

Step-by-step explanation:

This is in the form

y= mx+b where b is the y intercept

y = 3x-1

The y intercept is -1 so it crosses the y axis at -1

This eliminates graphs A and B

The slope is 3 which is positive so the graph will go up from left to right

This eliminates graph C
