Question 985902: I need help with two problems:
1. Write the point-slope form of the equation of the line which passes through (3,1) and is parallel to the line 3y = 2x - 3.
2. Multiply 2x%5E2 - 3x + 1 by 3x + 1 and then simplify.

1.
.
Slope intercept form: y=mx+b
Parallel lines have the same slope.
.
Find the slope (m) of given line
3y=2x-3
y=(2/3)x-1, m=2/3
.
Point-slope form:
%28y-y%5B1%5D%29=m%28x-x%5B1%5D%29
m=2/3 (from above), (x%5B1%5D,y%5B1%5D)=(3,1) (given)
ANSWER in point slope form:
%28y-1%29=%282%2F3%29%28x-3%29
.
PLEASE LIMIT TO ONE PROBLEM PER POST. IN THE FUTURE, I WILL ONLY ANSWER ONE.
THE TIME YOU SPEND TYPING ADDITIONAL QUESTIONS WILL BE WASTED.

2. Multiply 2x%5E2 - 3x + 1 by 3x + 1 and then simplify.
%282x%5E2-3x%2B1%29%283x%2B1%29
6x%5E3-9x%5E2%2B3x%2B2x%5E2-3x%2B1
6x%5E3-7x%5E2%2B1
