The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Reorder -2 and 2x.
y=2x-2
y=2x-2
Use the slope-intercept form to find the slope and y-intercept.

Find the values of m and b using the form y=mx+b.
m=2
b=-2
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 2
y-intercept: -2
Slope: 2
y-intercept: -2
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
