Find the intersection point for the following linear functions.

f(x) = 2x + 3
g(x) = -4x − 27

A. (5,-7)
B. (5,13)
C. (-5,-10)
D. (-5,-7)

Answer 1

D) (-5, - 7)

Explanation:

Because both lines intersect, they must share a point (have same x and y coordinates).

`2x + 3 = - 4x - 27`

`2x = - 4x - 30`

`6x = - 30`

`x = - 5`

Substite x for - 5 in any of the equations to find the y coordinate.

`y = 2( - 5) + 3`

`y = - 10 + 3`

`y = - 7`

The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)
