The data table represents the distance between a well-known lighthouse and a cruise ship over time. The cruise ship is travellin

Trava [24]

Find the velocity first, the "slope".

m=(y2-y1)/(x2-x1)

m=(95.5-53)/(4-2)

m=21.25 ? Your equations are wrong, I'll double check with another set of points...

m=(350.5-308)/(16-14)

m=21.25 LOL, yep none of your lines has the correct slope.

Anyway...

y=21.25x+b, using any point we can solve for the y-intercept, or "b", (2, 53)

53=21.25(2)+b

53=42.5+b

10.5=b so the distance to the lighthouse as a function of time is:

y=21.25x+10.5

So essentially, you should fire your teacher or burn that book you are using :)
