Lets 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:\[m=\frac{ h(5)h(3) }{ 53 }\]\[=\frac{ 1517 }{ 53 }\]\[=\frac{ 2 }{ 2 }= 1\]

Ok the last part is asking what is h(8). Just plug 8 in for t :D

so 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.

So this will help me get 20

so 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)

it 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.
