Question

What statements about the graphs of these two functions are true?

f(x)=-4x+3

g(x)=3x-4


A)Both graphs slant upwards and to the left


B)Only one graph intersects the y-axis above y=0


C)Both graphs have the same slope


D)Both graphs intersect the x-axis to the left of 0

Answer 1

B)Only one graph intersects the y-axis above y=0

Explanation:

Both functions are in y=mx+b. The y-intercept is b.

f(x) has the y-intercept 3. It intersects above y=0.

g(x) has the y-intercept -4. It intersects below y=0.

This means B is correct.
