Question

Pleasee help 25 POINTS AND BRAINLY PLEASE!! theres 4 graphs look at all pics below

Answer 1

ANSWER:

LAST GRAPH

EXPLANATION:

First, we need to know the equation. The equation is:

y=-2/5x-4.

"-4" is the "b" or the y-intercept. So, the line that is going through the y-intercept, or (0, -4) is the last two graphs. The "-2/5x" is the slope. Since it's a negative, it should be going from the top left to bottom right. Both graphs are. Now, we will look at the 2/5. When it states, "2/5" it means "y/x" NOT "x/y"

Since it's a negative, we will go down by 2 studs and go right by 5. (If it was positive, we will go up by 2 studs, but since this is a negative..)

Once you do that, you should see that the slope matches the last graph.

You can also tell by substituting points. For example, one is (5,-6) for the answer. You can substitue y as -6 and x as 5.

-6 = -2/5(5)-4

-6 = -6 / TRUE
