The equations of three lines are given below. Line 1: y = - 3/4 x + 3 Line 2/8 x - 6y = 2 Line 3/- 3y = 4x + 7 For each pair of lines, determine whether they are parallel, perpendicular, or neither.

No parallel lines

Lines 1 and 3 are perpendicular

Step-by-step explanation:

Given:

Required

Determine if they are parallel, perpendicular or not

The slope intercept of a line has the form:

Where

First, we calculate the slope of each lines

Compare the above to

Make -6y the subject

Divide through by -6

Compare the above to

Divide through by 3

Compare the above to

So, we have:

None of the slopes are the same, so none of the lines are parallel.

However, lines 1 and 3 are perpendicular.

This is shown below

When the slope of two lines satisfy the following condition, then they are  perpendicular.

This gives:

Convert / to *

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
