Answer: Table 3
A table of values x and y represents a linear function,
if the change in x is always proportional with the change in y:
For example:
x changes from 1 to 2, y changes from -3 to -5
that is, a change of 1 in the x-es, is a change of +2 in the y's.
x changes from 2 to 4, y changes from -5 to -9
that is, a change of 2 in x, is a change of +4 in the y's.
1, 2 and 2, 4 are proportional
Another way we can check that Table 3 is the only one representing a linear function, is the constant change in y:
as x takes the values : 1, 2, 3, 4, y becomes -3, -5, -7, -9
that is, a constant change of 1 in the x-es, means a constant change of +2 in the y's

Equation By Substitution/Elimination Method:
y = -3x + 4; y = 4x - 10
Let's solve your system by substitution.
y = −3x + 4; y = 4x − 10
Step: Solve y = −3x + 4 for y:
y = −3x + 4
Step: Substitute −3x + 4 for y in y = 4x − 10:
y = 4x − 10
−3x + 4 = 4x − 10
−3x + 4 + −4x =4x − 10 + −4x (Add -4x to both sides):
−7x + 4 = −10
−7x + 4 + −4 = − 10 + −4 (Add -4 to both sides):
-7x = -14
-7x/ -7 = -14/ -7 ( Divide both sides by -7):
x = 2
Step 2: Substitute 2 for x in y = −3x + 4:
y = −3x + 4
y = (−3)(2) + 4
y = −2 (Simplify both sides of the equation)
Answer:
x = 2
and
y = −2
