Which system of equations is represented by the graph?
a. y = x plus 4, over x plus 2
y = x + 4
b. y = x plus 4, over x plus 2
y = x − 4
c. y = x minus 4, over x plus 2
y = x + 4
d. y = x minus 4, over x plus 2
y = x − 4

The answer is D.

Step-by-step explanation:

Let's start by eliminating some wrong answers testing the values you are given in the red slope: (4, 0) and (-1, -5), taking into account that the coordinates are presented in the (x, y) format.

The options are y1=x+4 and y2=x-4

For (4, 0), x=4 so making the substitution x=4 in y1, we have y1= 4+4 = 8 or (4, 8), and (4, 0) ≠ (4, 8) thus all options showing y = x+4 can be discarded, leaving only B. and D.

Now let's test (-1, -5), with x=-1.

The options are and , if we test x=-1.

So for y1 (x=-1) = 3, thus (-1, 3). this discards option B, leaving option D. the only possible answer.

But still, running a test to see if D fits:

So y2 (x=-1) = -5, thus (-1, -5) just like we see in the image. This also fits with the other coordinate (4, 0), since y1 (x=4) = and y2 (x=4) = 0

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
