The equations of three lines are given below. Line 1: 2y = 5x+3

Line 2: y= 5/2 x+ 8

Line 3: 4x+10y = 6

Neither

Perpendicular

Parallel

Explanation:

Parallel lines have the same slope (y=mx+b, where m is the slope) and different y-intercepts, perpendicular lines have slopes that are opposite (negative/positive) reciprocals (multiplicative inverses) of each other.

Examples:

Parallel slopes: 3 and 3

Perpendicular slopes: 2 and

−

1

2

Neither: 4 and -8

To find out if the first two lines are parallel or perpendicular or neither, first put both equations into slope-intercept (y=mx+b) form.
