Question

For each pair of lines determine whether they are parallel, perpendicular, or neither

Answer 1

All lines are parallel.

Explanation:

Get each equation in Slope-Intercept form:

1. Divide both sides by 3:
`y=-(4)/(3)x+(7)/(3)`

2. No change

3. Subtract 8x and divide by 6 on both sides:
`y=-(4)/(3)x-(2)/(3)`

Notice:

a. All slopes are -4/3

b. All y-intercepts are different
