How can you determine if two lines are parallel from their equations?

Back

Convert both equations to slope-intercept form (y = mx + b) and compare their slopes.

How do you convert the equation 4x + 2y = 10 to slope-intercept form?

Back

Subtract 4x from both sides and then divide by 2 to get y = -2x + 5.
