Suppose that the water level of a river is 34 feet after 3 days of rain and 62 feet after 10 days of rain. The river was 22 feet before the rain began.

(y-34)=4(x+3)
(y-10)=1/4(x-62)
(y-62)=4(x-10)
4x-y=-22
3x+34y=22
10x-62y=22
Rate of change: 4 feet per day
Y-intercept: (0, 22)
Equation in Point-slope form: y - 34 = 4(x + 3)
Equation in Standard form: 4x - y = -22
are you sure?
Apologies for the mistake. Let's correct that.
Rate of change: 4 feet per day
Y-intercept: (0, 22)
Equation in Point-slope form: y - 22 = 4(x - 0)
Equation in Standard form: y = 4x + 22
