The answer is D. y = 2x
EXPLANATION - PLEASE READ THOROUGHLY
The equation should be in slope intercept form, y = mx + b, where m is the slope and b is the y-intercept. y-intercept means the point where the graph intercepts the y-axis.
The y-intercept is 0.
Now, to find the slope,
slope = rise/run
Find two random points on the line, such as (0,0) and (1,2)
The rise (change in y value) is 2, and the run (change in x value) is 1.
So, slope = rise/run = 2/1 = 2
Back to the slope-intercept equation:
y = mx+b
y = 2x + 0
y = 2x
