Question and answers in screenshots

Answer 1

Mind sorting out what you already know from what you don't?

Answer 2

Or, at least begin by asking questions whose answers will get you started ... ?

Answer 3

@lilkg77: Need your involvement. Please respond so as to get dialogue started.

Answer 4

for the first one
look at the graph again y2 = m(a + d) + b
simplify this and match the answer choice

Answer 5

@mathmale I honestly dont understand the at all so i dont think i can sort out what I know :(

Answer 6

We need to evaluate (find the value of) the slope of the line illustrated here. that requires evaluating the formula\[m=slope=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }.\]

Answer 7

Look carefully at the problem statement. You'll see a formula for \[y _{1}\]

Answer 8

which is as follows:

\[y _{1}=ma + b.\]

Answer 9

Do you see it?

Answer 10

Yes @mathmale

Answer 11

Hint: First we find "y sub 1"
Next, we find "y sub 2."

Answer 12

In\[y _{1}=ma + b.\]

Answer 13

Substitute y with 1?

Answer 14

the x-value is simply 'a'.

When we calculate "y sub 2," we use the x value "a+d". please review the problem and see if you can find this info there.

Answer 15

I see it @mathmale

Answer 16

Cool. Now, let's follow the pattern of \[y _{1}=mx+b \] ... using "a+d" for x instead of just "a":

Answer 17

\[y _{2}=m(a+d)+b\]

Answer 18

Here I've done 2 things: First, I replaced y sub 1 with y sub 2, and second, I replaced "x" with (a+d) (formerly, x was just "a", but now x is "(a+d). ) OK?

Answer 19

Okay

Answer 20

\[y _{2}=m(a+d)+b\]

Answer 21

Re-read the original problem, and then quickly review our discussion (above). What do you think you should be writing on that line in the problem (Step 2)?

Answer 22

y2= m(a+d+b)

Answer 23

Good, except that your right parenthesis should be after the 'd,' not after the 'b.'
Try again, please. What should we be writing on that line in the problem?

Answer 24

Well none of the answer choices has the right parenthesis after the d

Answer 25

Thats why i said y2= m(a+d+b) based on the answer choices in the question

Answer 26

If that's the case I honestly believe there's a typo in the set of possible answers.

Answer 27

Please look at Step 3. If you do this carefully, you can see that y sub 2 is given as m(a+b+d). While I disagree with this, you may have to choose the answer that resembles y sub 2 = m(a+d+b).

Answer 28

If you have access to a live teacher, I'd recommend that you discuss this problem with him or her and seek his or her input.

Answer 29

Okay i'll ask my teacher tommorow. Thanks for the help tho :)

Answer 30

@mathmale

Answer 31

if you followed my directions you would see the answer is D

Answer 32

I did not get a medal because I do not go in circles?
