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?
