Best ResponseYou've already chosen the best response.0Lets write it as Height being a function of time. They told us that we can model it as a linear function, so lets do that! :) It will be of the form: y=mx+b So we have a function: h(t)=mt+b So they gave us some information. h(3)=17 h(5)=15 We'll write these as ordered pairs. (3,17) (5,15). We'll find the m value (slope of our line) by using this form. \[m=\frac{ y_2y_1 }{ x_2x_1 }\]Which for us will be written like this:\[m=\frac{ h(5)h(3) }{ 53 }\]\[=\frac{ 1517 }{ 53 }\]\[=\frac{ 2 }{ 2 }= 1\]

Best ResponseYou've already chosen the best response.0so you've gotten the formula this far: h(t)=t+b So you can use some of your previous information to solve for b. Plug in the height and time (3,17), and solve for b.

Best ResponseYou've already chosen the best response.0so plugging in 3 and 17 gives us this equation 17=(3) + b b= 17 + 3 = 20 giving us an equation: h(t)=t+20 Then for your last part, find h(8)

Best ResponseYou've already chosen the best response.0it is a line, an equation can be written in the form: y=mx+b If you'll see from my previous notes, we found the slope of the equation (the m value) to be 1.
