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
ok, so slope intercept form is always y = mx +b - where m is the rate of change, and b is the constant
in this problem, they're giving you the "y" value - the height of the candle
so I"m going to make you work through this one, but it will be worth it
so they give you two equations with the two pieces of information in the word problem
in both cases, they give you y - the height of the candle, and x - the time since it was lit
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
can you solve for the two variables given those two equations?
let me know, brb
well srry i will try to do it i have to get ready for bed now
