Question

The solution to a system of equation is (1, 5).

Choose two equations that might make up the system.

(Select all that apply.)

y+ -3x-6
Y= 2x+3
Y= -7x+1
Y=x+4
Y=-2x-9

Answer 1

y = 2x + 3 and y = x + 4

Explanation:

the first equation:

y = -3x - 6

(5) =-3(1) - 6

5 = 3-6

5≠-3

second equation:

y = 2x + 3

(5) = 2(1) + 3

5 = 2 + 3

5 = 5

third equation:

y = -7x + 1

(5) = -7(1) + 1

5 = -7 + 1

5 ≠ -6

fourth equation:

y = x + 4

(5) = 1 + 4

5 = 5

last equation:

y = -2x - 9

(5) = -2(1) - 9

5 = -2 - 9

5 ≠ -11
