Question

kelli lights a candle after 4 minutes it's 8 inches tall after 16 minutes it's 5 inches tall which equation in slope intercept form represents the height of the candle after x minutes y=1/4x+9, y=1/4x+4, y=4x+24, or y=4x+4

Answer 1

ok, so slope intercept form is always y = mx +b - where m is the rate of change, and b is the constant

Answer 2

in this problem, they're giving you the "y" value - the height of the candle

Answer 3

so I"m going to make you work through this one, but it will be worth it

Answer 4

so they give you two equations with the two pieces of information in the word problem

Answer 5

in both cases, they give you y - the height of the candle, and x - the time since it was lit

Answer 6

1. 8 = m*4 +b - where m is the "slope" - or rate of change of the height of the candle
2. 5 = m*16 + b

Answer 7

can you solve for the two variables given those two equations?

Answer 8

let me know, brb

Answer 9

well srry i will try to do it i have to get ready for bed now
