Question

Write the equation of the line the passes through (1, -2) and (3, 4) in slope intercept form.​

Answer 1

y=3x-5

Explanation:

First find the slope, 4+2 over 3-1, giving you the slope of three

then set up your equation, y=3x+?

I played with the y=3x - part on the website desmos graphing calculator, I first inserted the points then found the slope and then played with the equation till it went through both the points.
