Question

What is x if a line passes though (2,5) ( x,3)

Answer 1

x = - 2

Explanation:

Givens

(2,5)

(x,3)

m = 1/2

Formula

m = (y2 - y1)/(x2 - x1)

Solution

y2 = 3

y1 = 5

x2 = x

x1 = 2

1/2 = (3 - 5)/(x - 2) Cross multiply

1*(x - 2) = 2 (-2) Combine and remove the brackets.

x - 2 = - 4 Add 2 to both sides

x = - 4 + 2

x = - 2
