y=3x-5

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=3

b=-5

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

Slope: 3

y-intercept: -5

Slope: 3

y-intercept: -5

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

Replace the variable x with 1 in the expression.

f(1)=3(1)-5

Simplify the result.

Multiply 3 by 1.

f(1)=3-5

Subtract 5 from 3.

f(1)=-2

The final answer is -2.

-2

-2

The y value at x=1 is -2.

y=-2

y=-2

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

Replace the variable x with 2 in the expression.

f(2)=3(2)-5

Simplify the result.

Multiply 3 by 2.

f(2)=6-5

Subtract 5 from 6.

f(2)=1

The final answer is 1.
