Answer:
y=2x-5
Explanation:
Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.
Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.
y=2x+b
Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.
