Parallel and perpendicular equations (! 40 points! )

3y - 7x = - 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

y = - x - 1 ← is in slope- intercept form

with slope m = -

Given a line with slope m then the slope of a line perpendicular to it is

= - = - =

Rearrange the given equations to find which slope matches m =

Consider 3y - 7x = - 9

Add 7x to both sides

3y = 7x - 9 ( divide all terms by 3 )

y = x - 3 ← in slope- intercept form

with slope =

Thus 3y - 7x = - 9 represents a perpendicular line

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
