Need help ASAP!! Will fan and medal!!

OpenStudy (133):

Just need to know if I'm right.

OpenStudy (133):

I'm thinking ether C or B mostly C

OpenStudy (anonymous):

i would go with B

OpenStudy (133):

I'm not to sure about that I think I'll wait for a second opinion cause I'm stuck between the two. @Nnesha

@shifuyanli

OpenStudy (freckles):

have you tried finding the slope ?

OpenStudy (freckles):

\[\text{ slope }= \frac{y_2-y_1}{x_2-x_1} \text{ we will call this value } m \\ y=mx+b \text{ so you can replace this } m \text{ with what you it to be in the previous line }\] \[\text{ Now find } b \text{ the } y-\text{ intercept } \\ \text{ by using a point on the line such as } (1,135)\]

OpenStudy (133):

So it would be C

OpenStudy (freckles):

I didn't say that and how did you get that?

OpenStudy (freckles):

first tell me the number you got the slope I assume it is 10 since you said C y=10x+b solve for b using the point (1,135)

OpenStudy (freckles):

replace x with 1 and y with 135 and solve for b

OpenStudy (anonymous):

It's A

OpenStudy (anonymous):

If you substitute for all the xes you her the correct answer

OpenStudy (133):

I know it's not A or D because the y-intercept has to be 135

OpenStudy (freckles):

the y-intercept is not 135

OpenStudy (freckles):

the y-intercept occurs when x is 0 (not 1)

OpenStudy (anonymous):

It is a. I'm one hundred percent sure

OpenStudy (anonymous):

@Joigirl help me.

OpenStudy (freckles):

y=10x+b (1,135) replace x with 1 and y with 135 135=10(1)+b 135=10+b can you solve this for b

OpenStudy (anonymous):

@Joigirl help ,eee

OpenStudy (133):

It was A thank you

OpenStudy (freckles):

A is right since 135-10 =125

OpenStudy (133):

Oh ok I get it now thanks!!
