Question

CAN SOMONR HELP ME?????? DOES SOMONE KNOW HOW TO DO THIS???????

Answer 1

see explanation

Explanation:

• Parallel lines have equal slopes

• The slopes of perpendicular lines are the negative reciprocal of each other

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 7x + 2y = 7 into this form

Subtract 7x from both sides

2y = - 7x + 7 ( divide all terms by 2 )

y = -
`(7)/(2)` x +
`(7)/(2)` ← in slope- intercept form

with slope m = -
`(7)/(2)`

Thus

slope of perpendicular line =
`(2)/(7)`

slope of parallel line = -
`(7)/(2)`
