13x-19

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=13

b=-19

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

Slope: 13

y-intercept: -19

Slope: 13

y-intercept: -19

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

Replace the variable x with 1 in the expression.

f(1)=13(1)-19

Simplify the result.

Multiply 13 by 1.

f(1)=13-19

Subtract 19 from 13.

f(1)=-6

The final answer is -6.

-6

-6

The y value at x=1 is -6.

y=-6

y=-6

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

Replace the variable x with 2 in the expression.

f(2)=13(2)-19

Simplify the result.

Multiply 13 by 2.

f(2)=26-19

Subtract 19 from 26.

f(2)=7

The final answer is 7.

7

7

The y value at x=2 is 7.

y=7

y=7
