Question

graph y=3x - 8

Answer 1

Do you know how to start this?

Answer 2

do you know how to find the x and y intercepts ?

Answer 3

Nope

Answer 4

The slope intercept form of an equation is y=mx+b where m is the slope and b is the y intercept.

Answer 5

remember that that the end piece will always be the slope. so for example in y=3x-8 your slope will be -8 so you would put that one the point of the graph and go up 3 and over right 1. since its just 3x itll be 3 and to the right 1 since its positive

Answer 6

Umm okay

Answer 7

do you get what im saying or no? @pinkylee

Answer 8

No

Answer 9

In y = mx + b form, the number in the m position is the slope and the number in the b position is the y intercept.
So the slope(m) is 3
The y intercept is -8...or (0,-8)
The x intercept can be found by subbing in 0 for y and solving for x
y = 3x - 8
0 = 3x - 8
-3x = -8
x = 8/3....so your x intercept is (8/3,0)...for graphing purposes, 8/3 = 2 2/3

so graph your points (0,-8) and (8/3,0)
now take your y int (0,-8)....and since the slope is 3, go up 3 and to the right 1 and up 3, and to the right 1...and you should cross the x axis at (8/3,0)

Answer 10

Thank u and I do

Answer 11

do you have to graph it right
so y = mx + b
like other people says m is slope always with x and b is y-intercept
to graph it always start with y-intercept
and y-intercept always on y -axis so draw point at -8 on y-axis
then slope rise/run your slope is 3/1 and becasue its positive so go up 3 step and then run 1 on right side

Answer 12

okay so does that mean the ordered pair is (0,-8)?

Answer 13

when you draw anything on y-axis x must be 0 :)

Answer 14

okay so was i right or wrong????

Answer 15

yes (0 , -8) is a orderpari

Answer 16

(0 ,8) is a y-intercept
there is another order pair like texaschic101
already told you x-intercept ( 8/3 , 0) so this is another pair

Answer 17

ohhhhhhhhhh okay now i understand

Answer 18

:) yep thats good :)

Answer 19

thank u :)

Answer 20

Answer 22

@thesmartone its okay

Answer 23

lol

Answer 24

but thank for it @thesmartone

Answer 25

No prob;em :)

Answer 26

problem*

Answer 27

yea guess so may i ask another question?

Answer 28

yes sure

Answer 29

what would be the order pair for y=-5x +19?

Answer 30

what is y-intercept ???

Answer 31

the what?

Answer 32

y-intercept
remember this equation y = mx + b here b is y-intercept
