Answer 2

yeap

Answer 3

WELL LE ME THINK

Answer 4

ok

Answer 5

y=ax+b. ok so now do the following. (1.5-3)/(1-2)=1.5 is the slope a=1.5
so now y=1.5x+b. Now substitute for example (2, 3) and count:
3=1.5*2+b, b=3-3=0. Can you do the following?

Answer 6

i got the slope of 1.5, is that correct?

Answer 7

yes

Answer 8

yay!

Answer 9

so wtite now the qation for me i want to check

Answer 10

y=1.5x+5?

Answer 11

uh no

Answer 12

1.5* not 5

Answer 13

y=1.5x+b

Answer 14

did you saw the value of b in my solving?

Answer 15

the y-interseptio if wrong it should be 0

Answer 16

y=1.5x+0?

Answer 17

yes but it is wwritten as just y=1.5x

Answer 18

it is when the y-interseption is 0

Answer 19

Yay. Thank you! You're awesome!
