y=4x-2.5

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=4

b=-2.5

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

Slope: 4

y-intercept: -2.5

Slope: 4

y-intercept: -2.5

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

Replace the variable x with 1 in the expression.

f(1)=4(1)-2.5

Simplify the result.

Multiply 4 by 1.

f(1)=4-2.5

Subtract 2.5 from 4.

f(1)=1.5

The final answer is 1.5.

1.5

1.5

The y value at x=1 is 1.5.

y=1.5

y=1.5

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)-2.5

Simplify the result.

Multiply 4 by 0.

f(0)=0-2.5

Subtract 2.5 from 0.

f(0)=-2.5

The final answer is -2.5.

-2.5

-2.5

The y value at x=0 is -2.5.

y=-2.5

y=-2.5
