Answer: y = 4x
Step-by-step explanation:
The slope-intercept form is written as y = mx + b, m is the slope, and b is the y-intercept, the y value when x is 0.
When x is 0, then y is 0. In this case, the y-intercept is 0.
Solve for slope, choose two-point, (0,0) and (1,4).
Slope = (y2 - y1)/(x2 - x1)
= (4 - 0)/(1 - 0)
= 4/1
=4.
Plug the slope and y-intercept in, where m is 4 and b is 0.
we get y = 4x + 0 = 4x
