Question

Which of the following equations would graph a line parallel to 3y=2x-x+5
A) 3y=x+1
B) y=x+1
C) y=2/3x+1
D) 3/2y=x+1

Answer 1

@RoseDryer

Answer 2

Combine like terms, ten put it in slope-intercept form

Answer 3

to check if one line is parallel to the other they need to have the same slope

Answer 4

I'm still confused..

Answer 5

3y=2x-x+5
3y=x+5
Divide by 3 on both side
y=1/3x+5/3
Find one that is parallel by finding one with the same slope. So get all into y=mx+b

Answer 6

A) 3y=x+1
divide by 3
y=1/3x+1/3
B) y=x+1
C) y=2/3x+1
D) 3/2y=x+1
I would multiply by 2 on both sides
3y=2x+2
divide by 3
y=2/3x+2/3

Answer 7

example
y = 2x + 3 is parallel with y = 2x + 5 because
the slope is the same ,
slope can be found by :

m = y2 - y1 / x2 - x1

or

by differenciation dy/dx

or by just comparison with the general form

y = mx + c where m is the slope

hope that clears the confusion.

Answer 8

okay so it would be A?

Answer 9

Yepp!!!!
