-3(x-4)-2

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=-3

b=10

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: -3

y-intercept: 10

Slope: -3

y-intercept: 10

Choose 3 to substitute in for x to find the ordered pair.

Replace the variable x with 3 in the expression.

f(3)=-3⋅3+10

Simplify the result.

Multiply -3 by 3.

f(3)=-9+10

Add -9 and 10.

f(3)=1

The final answer is 1.

1

y=1

Choose 2 to substitute in for x to find the ordered pair.

Replace the variable x with 2 in the expression.

f(2)=-3⋅2+10

Simplify the result.

Multiply -3 by 2.

f(2)=-6+10

Add -6 and 10.

f(2)=4

The final answer is 4.
