Question

ALGEBRA 1 HELP!

* I've tried putting this into slope intercept form using point slope formula, but it doesn't seem to make sense.*

Omar is on a diet to lose some weight. He is losing weight at a rate of 2 pounds per week. After 6 weeks, his weight is 204 pounds. Write and solve a linear equation to find how many weeks it will take Omar to reach his target wait of 180 pounds.

Answer 1

what did you get?

Answer 2

I got an ordered pair of 6,204

Answer 3

Then i plugged the numbers in

Answer 4

But when I tried to solve for 180 pounds it didn't add up

Answer 5

yes \((6,204)\) would be a point on the line
what is the slope?

Answer 6

m=2

Answer 7

what did you "plug the numbers in " to

Answer 8

y-204=2(x-6)

Answer 9

oooh lol, he is not gaining two pounds a week, he is losing two pounds a week!

Answer 10

your slope is making him fatter and fatter
no wonder you can't solve it

Answer 11

so is it negative 2?

Answer 12

yes, he is losing, not gaining

Answer 13

OHH ok Let me try it

Answer 14

k

Answer 15

@satellite73 I got y=-2+192

Answer 16

Then I subsituted the variables

Answer 17

and got x=6

Answer 18

so is it 12 weeks?

Answer 19

you want me to check?

Answer 20

Yea

Answer 21

there is a mistake somewhere

Answer 22

in the word problem?

Answer 23

or was it me
let me double check

Answer 24

\[y-204=-2(x-6)\] distribute get \[y-204=-2x+12\] i bet that was the mistake

Answer 25

add and get \[y=-2x+216\]

Answer 26

y - y1 = m(x - x1)
(6,204)....x1 = 6 and y1 = 204
slope(m) = 2
y - 204 = -2(x - 6)
y = -2x + 12 + 204
y = -2x + 216

180 = -2x + 216
180 - 216 = -2x
-36 = -2x
18 = x

not sure if I did that right...but I think your supposed to sub in 180 for y

Answer 27

ohhhh ok thank you both

Answer 28

yw

Answer 29

I got it added wrong
