capture 3

anonymous · Answer

How did you find it? @Troyboi13

anonymous · Answer

this is just a straight line, just plug x and y values and you will be able to draw it.

anonymous · Answer

so it is capture 3?

anonymous · Answer

its capture 2

anonymous · Answer

ok thanks

anonymous · Answer

would you like me to explain it, its very simple

anonymous · Answer

yes please

jwheele1 · Answer

You need to put the equation in slope intercept form first:
 y = mx+b

jwheele1 · Answer

do you know how to do that part?

anonymous · Answer

1. ok to see where the line cuts the y axis then just set x=0 and solve for y
2. to see where the line cuts the x axis then just set y=o and solve for x

thats it then just draw a straight line connecting them

anonymous · Answer

no im a little confused on that please explain :)

anonymous · Answer

I want to see if jwheele1 got the same answer as you did heedcom

jwheele1 · Answer

2x      – y     =    2
-2x                             -2x

               -y = 2 - 2x
                        OR
                 -y = -2x + 2
THEN divide both sides by the implied -1 in front of the y.
-y = -2x + 2
---   ----   ----
-1       -1      -1 


you get
y = 2x -2

jwheele1 · Answer

the form y = mx+b is the equation of a simple line.


the -2 is the y intercept so that is where you draw a dot on your grapoh

jwheele1 · Answer

TThan you will see that your slop is the number before the x...slope is M

jwheele1 · Answer

that number is 2.  When you are finding slope, you say the number is $$\frac{ 2 }{ 1}$$

anonymous · Answer

ok

jwheele1 · Answer

RISE OVER RUN.

you rise first before you run. 

you rise up two, and go to the right one

jwheele1 · Answer

from your dot

jwheele1 · Answer

For reference, you can keep going up two and over tot the right one and keep making your line infinately.

jwheele1 · Answer

2/1 is the same as -2/-1 so you can also go down two and to the left 1

jwheele1 · Answer

to answer your orig questio0n...

anonymous · Answer

Alright Thanks!! can you answer me another question

jwheele1 · Answer

looks like the third one down is the answer

jwheele1 · Answer

sure

anonymous · Answer

Write an equation of the line that passes through points (3, 7) and (5, 11).  (1 point)
y – 7 = 5(x – 3)
y – 7 = 2(x – 3)
y + 7 = 5(x – 3)
y + 7 = 2(x + 3)

jwheele1 · Answer

ok....so, first you must make an equation that looks like y = mx+b

jwheele1 · Answer

first draw graph

jwheele1 · Answer

you try with the draw feature using your ordered pairs

jwheele1 · Answer

WAIT

jwheele1 · Answer

there is an easier way
