Question

What is the equation of the line graphed below?

Answer 1

D

Explanation:

We can't really see any clear points apart from (0,8). That is why we will reason through the problem. We see that the y intercept is (0,8). Our equation needs to have -8 after the xs. That eliminates option A.

If we look at the second equation and we will put in x = 2, then y = -4. We can see that y isnť -4 on the graph though. We can eliminate B.

If we look at the second equation and we will put in x = 2, then y = -6. We can see that y isnť -6 on the graph though. We can eliminate C.

Only option remaining is D.

Answer 2

d

Explanation:

you can notice that the image of 0 using y = 3x-8 is -8 wich what we see on the graph

you can also notice that the image of 2.6 is 0 wich is what we see on the graph
