If
[tex]y = mx + b[/tex]
then m, the slope, is 5.5. We need to find b. When x = 11, y = 140, so:
[tex](140) = (5.5)(11) + b \\ 140 = 60.5 + b \\ b = 79.5[/tex]
We plug in the values for x, y, and m. Then, we simplify and subtract 60.5 from both sides.
This makes the equation
[tex]y = 5.5x + 79.5[/tex]
Or, in the context of this equation,
[tex]w(t) = 5.5t + 79.5[/tex]
[tex]y = mx + b[/tex]
