OpenStudy (triciaal):

post the question then someone will help

OpenStudy (anonymous):

Look at the graph shown:

OpenStudy (anonymous):

OpenStudy (anonymous):

Which equation best represents the line?

OpenStudy (anonymous):

Answer choices: y = 1 over 3. x − 1 y = 3x − 1 y = −x + 1 over 3. y = 3x + 1

pooja195 (pooja195):

Ok where is the starting point? where is the line hitting the y axis? What number? That will be known as out y intercept

OpenStudy (anonymous):

it hits the y axis at -1 ?

pooja195 (pooja195):

Perfect :) so far we have y=mx-1 now to find the slope. Slope= rise/run Can you find the slope? :)

OpenStudy (anonymous):

hmmm

OpenStudy (anonymous):

its something, 5 right ?

OpenStudy (anonymous):

(0,-1)

pooja195 (pooja195):

Nope |dw:1452827546493:dw|

pooja195 (pooja195):

How much are we rising? (going up)

OpenStudy (anonymous):

Find y when x=0 3x-1=y

pooja195 (pooja195):

^that is not what we need.

pooja195 (pooja195):

@Imverytired ?

OpenStudy (anonymous):

Idk I'm confused on this one

pooja195 (pooja195):

@Daniel56k Is showing you how to get the y intercept we do not need that.

OpenStudy (anonymous):

No she already have options down

pooja195 (pooja195):

We are looking for the slope. Slope=rise/run The amount of units we go up is the rise the amount of units we move to the left or right is known as the run.

OpenStudy (anonymous):

I know

pooja195 (pooja195):

|dw:1452827847706:dw| Using this can you tell me how much spaces we are moving up?

OpenStudy (anonymous):

@pooja195 we are looking for an equation that fits into the graph

pooja195 (pooja195):

I know that. That's what i'm doing.

OpenStudy (anonymous):

So 5, ?

pooja195 (pooja195):

Where are you getting 5 from? Can you explain?

OpenStudy (anonymous):

The top point is at 5

OpenStudy (anonymous):

I'm so sorry pooja. I'm rlly bad at mata

OpenStudy (anonymous):

*math

OpenStudy (anonymous):

That is the fastest way of solving the question during exam

pooja195 (pooja195):

|dw:1452827982842:dw|

OpenStudy (anonymous):

so 3,1

pooja195 (pooja195):

Its not a coordinate 3/1 <--slope is fractions until simplified 3 divided by 1=?

OpenStudy (anonymous):

3

pooja195 (pooja195):

Good now you know slope = 3 y=mx-1 m=slope slope=3 plug 3 in place of m what is our equation?

OpenStudy (anonymous):

y=3x-1

pooja195 (pooja195):

Well done

OpenStudy (anonymous):

pooja can u help with a couple more ? you are so helpful :) if not though its fine :)

pooja195 (pooja195):

I can ^_^

OpenStudy (anonymous):

ok tysm one sec

OpenStudy (anonymous):

Question: Two right triangles are graphed on a coordinate plane. One triangle has a vertical side of 2 and a horizontal side of 6. The other triangle has a vertical side of 10 and a horizontal side of 30. Could the hypotenuses of these two triangles lie along the same line? Answer Options: No, because they are not similar triangles No, because one is larger than the other Yes, because they are both right triangles Yes, because they are similar triangles

OpenStudy (anonymous):

I think it is b

pooja195 (pooja195):

Im confused on this one....i suggest you close this post and post this question onto a new post so that you can get someone else to post im sorry! :(

OpenStudy (anonymous):

Well i have 2 others and then ill get help on this one if u can help me with the others

OpenStudy (anonymous):

I gave u a medal @pooja195

pooja195 (pooja195):

ty :P @Imverytired still post it on another post.

OpenStudy (anonymous):

Ok can i tag you ? @pooja195

pooja195 (pooja195):

Sure.
