y=12x-9

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=12

b=-9

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

Slope: 12

y-intercept: -9

Slope: 12

y-intercept: -9

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

Replace the variable x with 2 in the expression.

f(2)=22-9

Simplify the result.

Divide 2 by 2.

f(2)=1-9

Subtract 9 from 1.

f(2)=-8

The final answer is -8.

-8

-8

The y value at x=2 is -8.

y=-8

y=-8

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

Replace the variable x with 0 in the expression.

f(0)=02-9

Simplify the result.

Divide 0 by 2.

f(0)=0-9

Subtract 9 from 0.

f(0)=-9

The final answer is -9.

-9

-9

The y value at x=0 is -9.

y=-9

y=-9
