HELP

Which of the equations is graphed below?
A. y = -x + 5
B. y = x – 5
C. y = x + 5
D. y = -x – 5

Answer 1

We can see that slope is positive, so it can be only B. or C.
y-intercept is - 5, so the answer is B. y = x – 5.

Answer 2

We can answer this by looking at the slope and y intercept.
The y intercept is -5. We know that we are now left with B and D.
The slope is positive as well, which means that B is the answer. We can check my putting 3 in for x. Y should be -2.
3-5=-2
So, B. Y=X-5.
