Question

If a linear equation is written in form y=1/2x-2, which method could be used to graph the line represented by the equation?

Answer 1

I would use the first option

Answer 2

u sure? ;)

Answer 3

what do you think?

Answer 4

i was also thinking about the first one

Answer 5

do you know what the way intercept mean?

Answer 6

in my opinion I am pretty sure.

Answer 7

I kinda forgot, Im learning it right know

Answer 8

(-2,0) , -2 represent x or y ?

Answer 9

x right???

Answer 10

it reps x

Answer 11

great now x intercept is when we put y=0 in our equation so could you solve that?

Answer 12

so like -2 times 0??

Answer 13

1 and 4 are very similar,
try both and the one that looks right; use it

Answer 14

y=(1/2)x-2
y=0
0=(1/2)x-2
(1/2)x=2
x=4
so the x-intercept is 4

Answer 15

ow thanks i kinda get it;)))

Answer 16

1 is not correct 100%

Answer 17

thanks you so much guys:)))

Answer 18

I just worked it, it is 4
sos for the delay

Answer 19

ow lol sorry haha

Answer 20

?

Answer 21

haha thanks guys ;))))

Answer 22

A candle is 17 in. tall after burning for 3 hours. After 5 hours, it is 15 in, tall. Write a linear equation to model the relationship between height h of the candle and time t. Predict how tall the candle will be after burning 8 hours.

Answer 23

h = reference height - (t - reference time)(rate)
h = 15 - (8 - 5)(1)
h = 15 - 3
h = 12 inches tall after 8 hours

Answer 24

thanks

Answer 25

thanks any more?

Answer 26

yep

Answer 27

The graph of g(x) is f(x) translated to the left 8 units and up 2 units. What is the function rule for g(x) given f(x)=x^2

Answer 28

I think it is: g(x) = (x + 6)2 - 5

Answer 29

thanks you so much:)))

Answer 30

thanks, any more?

Answer 31

nop im done thanks

Answer 32

k cool bye
