x = 5x=5

Explanation:

Proceed in the same way as if you were going to calculate the slope.

Write down the formula and substitute the values you have.

(y_2-y_1)/(x_2-x_1) = my2y1x2x1=m

(-2-6)/((x-3)) = (-4)/1 larr 26(x3)=41 simplify and solve for xx

(-8)/((x-3)) = (-4)/18(x3)=41

(-8)/(color(red)((x-3))) (div2)/(color(red)(div2)) = (-4)/color(red)(1)8(x3)÷2÷2=41

The numerators are fine, so consider only the denominators:

color(red)((x-3)/2 = 1)x32=1

x-3 = 2x3=2

x = 5x=5
