Options:

A. y=-3x-6

B. y=2x-23

C. y=-7x-16

D. y=x-17

E. y=-2x+9

Answer:

C. y=-7x-16

E. y=-2x+9

Explanation:

Given


(x,y) = (-5,19)

Required

Choose two equations

To do this, we simply substitute -5 for x in each of the options.

Whichever gives y=19 is true for the given solution


A.\ y=-3x-6


y=-3(-5)-6


y=15-6


y=9


B.\ y=2x-23


y=2(-5)-23


y=-10-23


y = -33


C.\ y=-7x-16


y=-7(-5)-16


y=35-16


y=19


D.\ y=x-17


y=-5-17


y=-22


E.\ y=-2x+9


y=-2(-5)+9


y=10+9


y = 19

Options C and E are true
