Question

Which of the following describes how to graph the line whose equation is y = 2/3x - 1?

Plot the point (0, -1), move up 3 and right 2, plot the point, and draw the line through these 2 points.

Plot the point (0, -1), move up 2 and right 3, plot the point, and draw the line through these 2 points.

Plot the point (-1, 0), move up 2 and right 3, plot the point, and draw the line through these 2 points.

I've put the equation in a graphing calculator and it doesn't line up with any of these

Answer 1

Hi ^_^
Welcome to openstudy! :-)
y=mx+b
b is the y intercept so the y part of the coordinate, where would we start off at what point?
(-1,0) OR (0,-1)

Answer 2

sorry, bare with me math is my worst subject....(0, -1)?

Answer 3

it's alright we are here to learn! :)
And actually that's correct! :D
Ok so we can eliminate C (the last one)
now, slope= rise/run
how much would we be rising?

Answer 4

Um by 2?

Answer 5

Good so we would move up 2
how much would move to the right?

Answer 6

Are you stuck?

Answer 7

3?

Answer 8

perfect!
So what's the answer?

Answer 9

The second one?
