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
Step-by-step explanation:
Given
[tex](x,y) = (-5,19)[/tex]
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
[tex]A.\ y=-3x-6[/tex]
[tex]y=-3(-5)-6[/tex]
[tex]y=15-6[/tex]
[tex]y=9[/tex]
[tex]B.\ y=2x-23[/tex]
[tex]y=2(-5)-23[/tex]
[tex]y=-10-23[/tex]
[tex]y = -33[/tex]
[tex]C.\ y=-7x-16[/tex]
[tex]y=-7(-5)-16[/tex]
[tex]y=35-16[/tex]
[tex]y=19[/tex]
[tex]D.\ y=x-17[/tex]
[tex]y=-5-17[/tex]
[tex]y=-22[/tex]
[tex]E.\ y=-2x+9[/tex]
[tex]y=-2(-5)+9[/tex]
[tex]y=10+9[/tex]
[tex]y = 19[/tex]
Options C and E are true
