Hello from MrBillDoesMath!

Answer:

Choice B. which is (3,-2)

Discussion:

Let's solve the simultaneous equations:

y = -2x + 4 (*)

y = x - 5 (**)

Substitute the value of y from (**) into (*):

y = -2x + 4 => y = x - 5

x-5 = -2x + 4 => add 2x to both sides

x + 2x -5 = 4 => add 5 to both sides

3x = 4 + 5 => simplify

3x = 9 => divide both sides by 3

x = 9/3 = 3

From (**) y = x - 5 = 3 -5 = -2. So the point of intersection is

(x,y) = (3,-2)

which is Choice B.

Thank you,

MrB
