y=43x-8

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=43

b=-8

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

Slope: 43

y-intercept: -8

Slope: 43

y-intercept: -8

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

Replace the variable x with 3 in the expression.

f(3)=4(3)3-8

Simplify the result.

Multiply 4 by 3.

f(3)=123-8

Divide 12 by 3.

f(3)=4-8

Subtract 8 from 4.

f(3)=-4

The final answer is -4.

-4

-4

The y value at x=3 is -4.

y=-4

y=-4

Choose 0 to substitute in for x to find the ordered pair.

Replace the variable x with 0 in the expression.

f(0)=4(0)3-8

Simplify the result.

Multiply 4 by 0.

f(0)=03-8

Divide 0 by 3.

f(0)=0-8

Subtract 8 from 0.

f(0)=-8

The final answer is -8.
