y=-98x-3

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=-98

b=-3

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

Slope: -98

y-intercept: -3

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

Replace the variable x with 0 in the expression.

f(0)=-9(0)8-3

Simplify the result.

Simplify each term.

Cancel the common factor of 0 and 8.

Factor 8 out of 9(0).

f(0)=-8(9⋅(0))8-3

Cancel the common factors.

Factor 8 out of 8.

f(0)=-8(9⋅(0))8(1)-3

Cancel the common factor.

f(0)=-8(9⋅(0))8⋅1-3

Rewrite the expression.

f(0)=-9⋅(0)1-3

Divide 9⋅(0) by 1.

f(0)=-(9⋅(0))-3

f(0)=-(9⋅(0))-3

f(0)=-(9⋅(0))-3

Multiply 9 by 0.

f(0)=-0-3

Multiply -1 by 0.

f(0)=0-3

f(0)=0-3

Subtract 3 from 0.

f(0)=-3

The final answer is -3.

Choose 1 to substitute in for x to find the ordered pair.

Replace the variable x with 1 in the expression.

f(1)=-9(1)8-3

Simplify the result.

Multiply 9 by 1.

f(1)=-98-3

To write -3 as a fraction with a common denominator, multiply by 88.

f(1)=-98-3⋅88

Combine -3 and 88.

f(1)=-98+-3⋅88

Combine the numerators over the common denominator.

f(1)=-9-3⋅88

Simplify the numerator.

Multiply -3 by 8.

f(1)=-9-248

Subtract 24 from -9.

f(1)=-338

f(1)=-338

Move the negative in front of the fraction.

f(1)=-338

The final answer is -338.
