y=3-4x

Reorder 3 and -4x.

y=-4x+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=-4

b=3

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

Slope: -4

y-intercept: 3

Slope: -4

y-intercept: 3

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+3

Simplify the result.

Multiply -4 by 1.

f(1)=-4+3

Add -4 and 3.

f(1)=-1

The final answer is -1.

-1

-1

The y value at x=1 is -1.

y=-1

y=-1

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+3

Simplify the result.

Multiply -4 by 0.

f(0)=0+3

Add 0 and 3.

f(0)=3

The final answer is 3.
