@Tuta

Answer 2

i vote c

Answer 3

Do you agree with him @Tuta?

Answer 4

@Hunus

Answer 5

@campbell_st

Answer 6

Do you think it's c @campbell_st ?

Answer 7

i am always sure that is one thing

Answer 8

well the y-intercept appears to be 5... so that rules out A and C

find the slope

m = change in y (61 - 33)/change in x(8 - 4)

then use y = mx + b m = slope which you can calculate and y is 5...

hope it helps

Answer 9

nooo you r going to get a bad grade if listen to him

Answer 10

@Algorithmic

Answer 11

I really need your help your the best i know

Answer 12

i thought u asked me

Answer 13

:/

Answer 14

I'm really confused and algorithmic has helped me alot

Answer 15

just do the math.....

the general line is

y=mx + b

m is the slope...... and b is where the line cuts the y axis...

so look at the line, where does is cut or start on the vertical axis..?

Answer 16

@campbell_st has it correct. What do you not understand?

Answer 17

Ok so it starts at 4,33 and ends at 8,61 i just don't understand what im suppost to plug in im awful at math i appologize :/

Answer 18

sorry i had a test
i hope u got help

Answer 19

And i think chordae might have given me the wrong answer on a question i asked previously

Answer 20

"find the slope m = change in y (61 - 33)/change in x(8 - 4)"
So:
\(61 - 33 = 28\)
\(24 \div 4 = 7\)

Input it into the equation of:
\[y = mx + c\]
\[y = 7x + 5\]

Answer 21

that's why open study wants people to give help... not answers...

Answer 22

^ Exactly.
