Answer:
y=2x
Step-by-step explanation:
The equation for slop-intercept form is y=mx+b where m is the slope and b is the y-intercept.
2 represents the rise/over since you rise 2 units (up) and run 1 unit (to the right). So the slope is 2/1 or just 2, and then you multiply it by x to get 2x.
The line starts at the origin (0,0), so the y-intercept would be 0. They didn't say y=2x+0 because the + 0 wouldn't change the line.
