Answer 1

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 2

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.
