consider the slope-intercept form y =mx + b, where m is the slope and be is the y-intercept.
What is the slope (m) of the graph? The points move up 4 and over 2, so the slope equals 4 ÷ 2 = 2. Option B is the only graph with a slope of 2, so we already know that the answer is B) y=2x.
To confirm, check the y-intercept. You can see that the graph will pass through the point (0,0), which means b=0.
