-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.

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.
