y = mx + b m is slope y = 3x  1 3 is slope Parallel lines have the same slope. Slope of Perpendicular lines is the opposite reciprocal...change to the opposite sign and find the reciprocal. ex: 2 to 1/2

So what is the slope of the parallel line?

the slope is 3

Oh. okay. positive 1? Since I had to change it

The opposite reciprocal of 3 would be a positive 1/3. You switch signs(from  to +). 3 is the same as 3/1...and you find the reciprocal, which is 1/3.  Lets find the equation for the parallel line first. You have a slope of 3 and the given point is (3, 1).

Yes, I do know. Just was a little confused at the start

Ok (: So are you familiar with PointSlope form?

Why'd it delete?! y  y1 = m(x  x1) m is slope x1 and y1 are the values of the point, (x, y) (3, 1) Slope is 3. y  1 = 3(x  3)

Weird. yeah it deleted

Strange :/ Okay, so we have to change that^ into SlopeIntercept form. Distribute the 3. Solve for y. y  1 = 3(x  3) y  1 = 3x + 9 Add 1 to both sides. y = 3x + 10 ^There is the equation for the parallel line.

Yea, so you don't really have to go through finding the perpendicular line. (;

Vivian combined different amounts of white paint, blue paint, and green paint to make 145 milliliters (ml) of paint of a new shade. The amount of white paint was x ml. The amount of blue paint was 10 ml less than twice the amount of white paint, and the amount of green paint was half the amount of blue paint. This is represented in the equation below. x + (2x – 10) + 1/2 (2x – 10) = 145 What was the difference in the amounts of white paint and blue paint Vivian combined? 30 ml 35 ml 40 ml 45 ml
