Answer:
y=-2x+2
Explanation:
The slope is -2x, meaning that the y-intercept can be found by working backwards from the given point. If the y value of the point is 4, subtracting 2 to get you to the point (0, 2) would provide the y-intercept.
Slope Intercept form is y=mx+b (m is the slope, x is the entered value, b is the y intercept)
