Answer 1

Is -7/8 the slope ?

Answer 2

yes

Answer 3

ok
do you know the formula of creating a line by knowing the slope and a point ?

Answer 4

i can do these as long as its not a fraction one i cant grasp the fraction and at the end on how to know whether to add or subtract

Answer 5

i know the end will come out to be y=-7/8x and the rest i have no clue

Answer 6

ok
simply you have to substitute by m= -7/8 in the equation
y=mx+b

Answer 7

i understand that. -7/8 (-2)+b, from here im confused

Answer 8

\[y=\frac{ -7 }{ 8 }x+b\]

Answer 9

then to find b let x=-2 and y=6

Answer 10

ok got that

Answer 11

got b ?

Answer 12

no after that last step is where i get confused

Answer 13

let x=-2 and y=6 in the equation above and calculate b

Answer 14

14/8 ?

Answer 15

how ?

Answer 16

see this is where i have no clue how to do this

Answer 17

i multiplied -7/8 (-2)

Answer 18
