Question

How do you find x and y

Answer 1

(-5,38)

Explanation:

Equate the two functions

x^2 - 2x + 3 = -2x + 28

Rearrange and make one side zero.

x^2 - 2x + 2x + 3 - 28 = 0

x^2 - 25 = 0

(x-5)(x+5) = 0

x = 5, -5

We already have the coordinates with x = 5

Using x = -5 in any function, find y

y = -2x + 28

y = -2(-5) + 28 = 10 + 28 = 38
