Question

Quincy created a the table of x and y values shown here.

X 1 2 3 4
y -6 -4 -2 0
Which equation represents the relationship between the x values and the y values in the table?
A y=x+7
By=6x-1
Cy=3x-9
Dy=2x-8

Answer 1

D. y=2x-8
all you need to do is plug the x and y values given in the table into the x and y of the equations
for example, if we used equation A. y=x+7 we would plug in our first set of x and y values: -6=1+7 but once you solve it you find it’s not true: -6≠8 so you know it isnt equation A
if we use equation D. y=2x-8 , plug in our values: -6=2(1)-8 it is true since 2-8=-6, giving us -6=-6

Answer 2

D

Explanation:

the answer is y=2x-8

just sub in the a number from the x column in the equation and whatever you get from that is what should b in the y column
