Answer:
A
Step-by-step explanation:
-4 is the y-intercept, so there will always be an arrow that crosses over that point. And for the slope (2x) you need to go up two places from the y-intercept and then one to the right :)
The 2 in 2x-4 tells us that the line is rising, so that disqualifies answer B and C.
The -4 tells us the line passes the y axis at -4, so that disqualifies C and D.
Leaves A!
