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=-1

b=24

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

Slope: -1

y-intercept: 24

Slope: -1

y-intercept: 24

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

Replace the variable x with 3 in the expression.

f(3)=-(3)+24

Simplify the result.

Multiply -1 by 3.

f(3)=-3+24

Add -3 and 24.

f(3)=21

The final answer is 21.

21

21

The y value at x=3 is 21.

y=21

y=21

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

Replace the variable x with 2 in the expression.

f(2)=-(2)+24

Simplify the result.

Multiply -1 by 2.

f(2)=-2+24

Add -2 and 24.

f(2)=22

The final answer is 22.
