Suppose parametric equations for the line segment between (8,−1) and (0,10) have the form
x(t)=a+bt
y(t)=c+dt
If the parametric curve starts at
(8,−1) when t=0 and ends at (0,10)at t=1, then find a, b, c, and d.

Aclothing store has the sign shown in the shop window. pani sees the sign and wants to buy 3 shirts and 2 pairs of jeans. the cost of each shirt before the discount is $12, and the cost of each pair of jeans is $19 before the discount. write and simplify an expression to find the amount pani pays if a $3 discount is applied to her total
