Question

Write an equation of a line in slope intercept form that is parallel to y = -3x+6 and passes through the points (2,-5)

Answer 1

Fist you need to take the negative reciprocal of the slope.
The slope of your original equation is -3 there for the negative reciprocal is \[\frac{ 1 }{ 3 }\]

Answer 2

i thought parallel is the same slope

Answer 3

oops.. I read perpendicular... ok scratch that last post.

Answer 4

okay so parallel... the slope is the same so you need to plug in 2 in for x and -5 in for y, but take out the +6 and make it +b.... so your equation will look like \[-5=-3(2)+b\]

Answer 5

now solve for b...

Answer 6

your answer should be b=1

Answer 7

now your new equation is y=-3x+1

Answer 8

thanks i understand it now

Answer 9

i have another question similar to that but it is perpendicular. would i do the same process just change the slope

Answer 10

yep... you the negative reciprocal for the slope.
