y=-2x-4

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=-2

b=-4

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

Slope: -2

y-intercept: -4

Slope: -2

y-intercept: -4

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

Replace the variable x with 0 in the expression.

f(0)=-2⋅0-4

Simplify the result.

Multiply -2 by 0.

f(0)=0-4

Subtract 4 from 0.

f(0)=-4

The final answer is -4.

-4

-4

The y value at x=0 is -4.

y=-4

y=-4

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

Replace the variable x with 1 in the expression.

f(1)=-2⋅1-4

Simplify the result.

Multiply -2 by 1.

f(1)=-2-4

Subtract 4 from -2.

f(1)=-6

The final answer is -6.
