Question

Show your work to prove that the equation y = 12x + 8 correctly represents the function for the data in this table.

Answer 1

u have three values for x. replace them in the equation and if u get the values already provided for y, then u got the prove.

Answer 2

replace each value of x into the equation. do the arithmetic and see if u get the corresponding value for y.

Answer 3

for instance, if x=2 then
\[\large y=12x+8=12\cdot2+8=24+8=32 \]
as expected.

do the same with the other two values of x.
