Question

Identify the system of equations that have the point (3,-1) as their point of intersection A) y=3x-10 y=x-1. B) y=3x-10 y=2x-7 C) y=5x-16 y=x-4

Answer 1

B) and C)

Explanation:

Given our point of intersection at (3, -1), we will test these points for both equations of each set

A) y = 3(3) -10

y = -1

y = (3) -1

y = 2

A does not satisfy all conditions

B) y = 3(3) -10

y = -1

y = 2(3) - 7

y = -1

B satisfies all conditions

C) y = 5(3) - 16

y = -1

y = (3) - 4

y = -1

C satisfies all conditions
