Help with a couple questions ?

@pooja195
post the question then someone will help
Look at the graph shown:
Which equation best represents the line?
Answer choices: y = 1 over 3. x − 1 y = 3x − 1 y = −x + 1 over 3. y = 3x + 1
Ok where is the starting point? where is the line hitting the y axis? What number? That will be known as out y intercept
it hits the y axis at -1 ?
Perfect :) so far we have y=mx-1 now to find the slope. Slope= rise/run Can you find the slope? :)
hmmm
its something, 5 right ?
(0,-1)
Nope |dw:1452827546493:dw|
How much are we rising? (going up)
Find y when x=0 3x-1=y
^that is not what we need.
@Imverytired ?
Idk I'm confused on this one
@Daniel56k Is showing you how to get the y intercept we do not need that.
No she already have options down
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.
I know
|dw:1452827847706:dw| Using this can you tell me how much spaces we are moving up?
@pooja195 we are looking for an equation that fits into the graph
I know that. That's what i'm doing.
So 5, ?
Where are you getting 5 from? Can you explain?
The top point is at 5
I'm so sorry pooja. I'm rlly bad at mata
*math
That is the fastest way of solving the question during exam
|dw:1452827982842:dw|
so 3,1
Its not a coordinate 3/1 <--slope is fractions until simplified 3 divided by 1=?
3
Good now you know slope = 3 y=mx-1 m=slope slope=3 plug 3 in place of m what is our equation?
y=3x-1
Well done
pooja can u help with a couple more ? you are so helpful :) if not though its fine :)
I can ^_^
ok tysm one sec
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
I think it is b
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! :(
Well i have 2 others and then ill get help on this one if u can help me with the others
I gave u a medal @pooja195
ty :P @Imverytired still post it on another post.
Ok can i tag you ? @pooja195
Sure.
