Question

Which is the graph of y = 2.5x? A. B. C. D.

Answer 1

The answer is D. because first you got solve the problem.

y=2.5x
(turn y to 0)
0= 2.5x
÷2.5  ÷2.5
_________
0=x

So we got one answer (0,0) 

y=2.5x
(turn x to 0)
y= 2.5(0)
 y=2.5

(2.5, 0)

When you do (0,0) (2.5,0) on the graph it will look like D.)
