Question

Can someone please help? Trying to get exempt from the final! I'll fan whoever answers

Answer 1

You have to write the equation in slope-intercept form?

Answer 2

i know that, i don't know how to.

Answer 3

y=mx+b is slope intercept form
b= y intercept and in this case b=3
m=slope to find the slope find 2 coordinates and replace them into the formula
x1-x2/y1-y2

Answer 4

okay so whats the equation for Slope intercept form??

@_ashleeey

Answer 5

Of course, you WILL have to do two equations and decide which to use when.

The one with positive slope lends itself to the Intercept Form. Just write it down. \(\dfrac{x}{1}+\dfrac{y}{-1} = 1\).

Answer 6

mx + b @claritamontano

Answer 7

x and y would be (4,3) right? @tkhunny

Answer 8

okay so what does M stand for?

Answer 9

x?

Answer 10

mx+b=y

Answer 11

thats the equation right.
So what you do is you find what the slope is ( m)

Answer 12

isnt it 4?

Answer 13

(4,3) is a very important point. That point must be included in both equations. It is the ONLY point with this property.

Answer 14

So how you do that, you go o a point on the graph that hits a point exactly with two numbers and then do rise over run. until you hit another point.

Answer 15

How did you get 4???

Answer 16

okay, so its (4,3) right now, and i go up two right?

Answer 17

the x value

Answer 18

Obvious points for the positive slope are (0,-1)(1,0)(4,3)
Obvious points for the negative slope are (4,3)(7,0)

Answer 19

but m isnt the x value its the slop and to find the slope you do rise over run

Answer 20

did you find all those on the line? @tkhunny and @claritamontano okay but i start on 4,3 then do rise over run from there right?

Answer 21

no, if you start there, you wont get anything cause there is no line that goes up. Start at
9, -2 and do rise over run

Answer 22

i ended up figuring this one out, thank you, can you help with my last two though?

Answer 23

yeah sure! Open a new one tho
