Answer:
D
Step-by-step explanation:
First let's notice a couple things:
- All the answers are in y = mx + b form
- Two of the answers don't have a value for b
- Pretty much all of the answers have a different m value
So let's go in order of our realizations.
Let's start with figuring out what b is. By simply looking at the graph, we can see that b = 0, because the line starts at (0, 0). Remember that b is when the line crosses the y axis, and our y value at x = 0 is 0.
This crosses out A and B.
Now let's find m, aka the slope. We can figure this out using the slope formula:
Awesome! So we've figured out that m = 7/2. This means our answer has to be D.
