Answer:

D. none of these

Step-by-step explanation:

y = mx + b

b is the y-intercept. on the graph we can see the line crosses the y-axis at -3

so y = mx - 3

m is the slope. slope is rise over run (how far up, rise, and then over, run, you need to go to get from one point on the line to the next). If we start at the y-intercept we have to go up 1 over 1 to get to the next point on the line. this makes the slope 1.

therefore the actual equation is y = x - 3

It’s not D it’s B. y = 1/2x - 3 since the line goes through -3 on the graph we can eliminate C and D. And we can eliminate A cuz the graph will show in the opposite direction.

In conclusion ur answer is B. :)
