y=-7x+47

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=-7

b=47

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

Slope: -7

y-intercept: 47

Slope: -7

y-intercept: 47

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

Replace the variable x with 3 in the expression.

f(3)=-7⋅3+47

Simplify the result.

Multiply -7 by 3.

f(3)=-21+47

Add -21 and 47.

f(3)=26

The final answer is 26.

26

26

The y value at x=3 is 26.

y=26
