B. 3x - 4 = 5x - 10
C. 3x + 4 = 5x + 10
D. 3x - 4 = 5x + 10

Answer 2

@campbell_st Can you check if I'm right? I think it's C

Answer 3

simply have a look and decide where the lines cut the y-axis....

what do you think...?

Answer 4

i can't really tell...

Answer 5

just read of the scale.... and use your best guess...

Answer 6

I think it crosses the y-axis at (0,1)

Answer 7

well the major ticks are in units of 5.... do one line cuts the y-axis just below 5...

any guesses..?

Answer 8

yeah it's right below 5, which is why i think the answer is C. am i right?

Answer 9

ok... so by saying its y = 4 it means you have eliminated B and D as answers

the general form of the line is

y = mx + b

so you have 1 line as

y = mx + 4

now look at the other line and tell me where it cuts the y-axis..?

Answer 10

(0, 10)

Answer 11

your choices are between A and C

are you sure its at 10...? so its above 4

Answer 12

just look at the graph again

Answer 13

remember the y-axis is the vertical one.

Answer 14

Yeah I'm pretty sure it's at 10...what is it?

Answer 15

so by what you are saying the graph looks like

Answer 16

Oh oops....so -10?

Answer 17

ok... so the 2nd line is in the form

y = ax - 10

y = mx + 4

so which answer...?

Answer 18

A?

Answer 19

remember you are only choosing between A and C

Answer 20

that's correct
