Answer:
P(t) = -1/3 + 1
Step-by-step explanation:
to find this out, we must use the slope perpendicular to 3
perpendicular slopes are the slope's reciprocal's negative, which in this case it is -1/3
to find the line with the points (3,1), we simply use the equation y = -1/3x + b and then plug them in
1 = -1/3(3) + b
1 = -1 + b
b = 2
the y intercept is 2 and so we can write the equation like this:
P(t) = -1/3t + 2
