Find equation of line

  • (1,1)
  • (3,7)

Slope

  • m=7-1/3-1
  • m=6/2
  • m=3

Equation

  • y-1=3(x-1)
  • y-1=3x-3
  • y=3x-2

Now

put y=-2

  • 3x-2=-2
  • 3x=0
  • x=0

Answer:

x=0. The explanation is below.

Explanation:

So, it is run 2 rise 6. We can fact-check that with 1 to 3 to 5 and 1 to 7 to 13. So, the slope is 3 because of rise over run. So, we can make an equation with y = mx + b. m = 3 because that is the slope. 1=3(1) + b. b=-2. So, the equation is y=3x-2. We can find any x using y and vice versa if we find the equation.

For this part, -2=3x-2. 3x=0. x=0.
