For the first one, do you know the equation or slope atleast of each line?

heyitslizzy13 · Answer

for the one on the far right i believe m=2

heyitslizzy13 · Answer

and the one on the left m= -1/2 ?

fortytherapper · Answer

Correct on the first one, the second one is slightly off with your numerator though

Looking at the answer choices and the graphs for the first one, I don't see an answer, because neither of the graphs have a slope of 1

heyitslizzy13 · Answer

what is the slope for the second one?

fortytherapper · Answer

You go right 3 and down 2 to get an exact slope, making it -3/2

fortytherapper · Answer

The answer choices ask for -x or x, which is -1 or 1, but neither line shows this

heyitslizzy13 · Answer

isn't it rise over run though? i'm kind of confused

heyitslizzy13 · Answer

oh wait no, okay i got it :)

heyitslizzy13 · Answer

so none of the answers are correct?

fortytherapper · Answer

I don't see the answer on the first one. Not sure if the teacher messed up or something

heyitslizzy13 · Answer

aw okay thanks, could you help me on the second problem ?

fortytherapper · Answer

Sure
After doing the second one, that one has an answer

So for the X>2 part of the peicewise, you have when x = 0, y= 1 and when x= -2, y = 5

From there, would you know how to find the slope?

heyitslizzy13 · Answer

how did you get those points?

fortytherapper · Answer

So when we look at the second one, we have to dots

Now, when we're on the X axis (The one going horizontally), what does y always equal?

And when were on the Y axis, what does x always equal?

heyitslizzy13 · Answer

5 and 0?

fortytherapper · Answer

Right on the second one. The x would always equal 0 since y axis is always a straight line

For the first answer though, the x axis is always a straight line too, correct? So y would also equal what?

heyitslizzy13 · Answer

0?

fortytherapper · Answer

Exactly!

So for this problem, the lower dot shows a 1 on the y axis, so we have y=1. Since the dot is on one of those axis (The straight line), what would the x coordinate be?

fortytherapper · Answer

Correct, so the first point was (0,1), aka x = 0, and y =1

Now for the second point. The dot has two numbers associated with it. You always do the X number first and then the Y

heyitslizzy13 · Answer

okay but shouldn't that 2 be a negative two?.. since its going left

heyitslizzy13 · Answer

like (-2,5)
