y=2x
Step 1
Use the slope-intercept form to find the slope and y-intercept.

Step 1.1
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Step 1.2
Find the values of m and b using the form y=mx+b.
m=2
b=0
Step 1.3
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 2
y-intercept: (0,0)
Slope: 2
y-intercept: (0,0)
Step 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.
