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=12
b=-4
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 12
y-intercept: -4
Slope: 12
y-intercept: -4
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

Multiply 12 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.

Multiply 12 by 1.
f(1)=12-4
Subtract 4 from 12.
f(1)=8
The final answer is 8.
