Question

Use the slope and y-intercept to graph each equation. -2(3x-4)+y=0 What is the slope and y-intercept and how do i find it?

Answer 1

Any ideas?

Answer 2

um first distribute?

Answer 3

@Lizzychey The first thing you need to know is what form do you want to put the given equation into?

Answer 4

y=mx+b

Answer 5

Very good. :)

This is called the slope intercept form where m is the slope and b is the y-intercept.

Answer 6

right but how am i suppose to find them when its -2(3x-4)+y=0 its nowhere near y=mx+b

Answer 7

distribute the -2 (3x -4) + y = 0

Answer 8

-6x+8+y=0

Answer 9

subtract 8 from both sides

Answer 10

why not -6x?

Answer 11

not yet

Answer 12

ok so -6x+y=-8

Answer 13

Good, now add 6x to both sides.

Answer 14

then add -6x to both sides which gives me y=6x-8

Answer 15

6x +(-6x) = 0

Answer 16

ok so now its in y=mx+b form so the slope is 6 and the y-intercept is -8?

Answer 17

so the 2 points are (0,-8), (1,-2) ?

Answer 18

Correct :)

Answer 19

Yay!! Thank you! :)

Answer 20
