Question

complete the table below and write a rule relating x and y

x -3,-2,-1,0,1,2,3,4
y -7, ?, ?, 2, 5,?,?,14

Answer 1

try to find the equation of the line through (0,2) and (1,5)

Answer 2

x=3/1+2
?

Answer 3

very close

Answer 4

but no

Answer 5

remember that y = mx+b is the general slope intercept form

Answer 6

right

Answer 7

what did you get for the slope

Answer 8

1/3

Answer 9

incorrect

Answer 10

oh

Answer 11

3/1?

Answer 12

yes or 3

Answer 13

y-intercept is what?

Answer 14

1

Answer 15

i'm not sure

Answer 16

the y-intercept is the y value of the point when x = 0

Answer 17

ooh ok, then 2?

Answer 18

so b = 2

Answer 19

m = 3, b = 2

Answer 20

the equation y = mx+b turns into y = 3x+2

Answer 21

you can now determine the other y values

Answer 22

oooh thank you I understand now

Answer 23
