Answer:
D. 2x - y = 4
Explanation:
Note that the line has a positive slope since y increases as x increases
We can easily eliminate A and B
That leaves C and D
The line passes through (0,-4) so the y-intercept is -4
The equation of a line in slope intercept form is
y = mx + b where m is the slope and b the y-intercept
Rewrite C and D so that y is on the LHS and the other terms are on the RHS
C=> y = -2x + 4 ==> slope is negative; reject
Only choice left is D
Just to be sure
D=> -y = -2x + 4 (subtract 2x on both sides)
=> y = 2x - 4 (multiply by -1)
