y=−2+3x4y=-2+3x4

Rewrite in slope-intercept form.

Tap for more steps...

y=34x−2y=34x-2

Use the slope-intercept form to find the slope and y-intercept.

Tap for more steps...

Slope: 3434

y-intercept: (0,−2)(0,-2)

Any line can be graphed using two points. Select two xx values, and plug them into the equation to find the corresponding yy values.

Tap for more steps...

xy0−2830xy0-2830

Graph the line using the slope and the y-intercept, or the points.

Slope: 3434

y-intercept: (0,−2)(0,-2)

xy0−2830xy0-2830

3x−4y=83x-4y=8

and
