Question

I really need help coming up with the equation to this problem. Help please ! A snail oozes at a uniforn1 speed along the crossbar of a picket fence. On day zero, it is at the third picket; on day five, it has reached the tenth picket. Write a linear model of the snail's position on day n. In what units is the slope measured?

Answer 1

units of slope : fenceposts/day

Answer 2

day zero, third picket (x, y) = (0, 3)
day five, tenth picket (x, y) = (5, 10)

slope = (y^2-y^1) / (x^2-x^1)

(10-3) / (5-0)
slope = 7/5

To solve for the equation of the line, you can use either y = mx + b (slope-intercept form) or (y-y1) = m (x-x1) (point-slope form).

Thanks so much !
