a shopper at a clearance sale is to discover some cookie jars on sale for $19 each. the original price tags read $20. what is the discount percentage?

write your answer using a percent sign (%).

To find the percent of change, divide the difference by the original amount.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
