Question

Find the intersection point for the following linear functions.

f(x) = 2x + 3
g(x) = -4x − 27

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

Answer 1

d

Explanation:

Answer 2

(-5,-7)

Explanation:

To find points of intersection, first set the two equations equal and then solve for x. Then substitute that x back into either equation for the complete point of intersection.

2x + 3 = -4x - 27

6x = -30

x = -5

2(-5)+3 = -10 + 3 = -7 (substituting our solution into f(x) here)
