The answer is 100.
You start by making a formula:
.80(x) = 80,
As we know the discount is 20% off, which makes the price actually 80% of what it originally was. Convert percent to a decimal gets you that .80
Reverse the process — 80/0.80 = 100
Slope of the line formed by points (-1,-2) and (3,-3) is 
Step-by-step explanation:
We need to find slope of the line formed by points (-1,-2) and (3,-3)
Finding slope:
The formula used is:

1/5 = 20%
% sponge cakes = 100 - 50 - 20 = 100 - 70 = 30% Answer
Answer:
The y intercepts is -2
y = 1x-2
Step-by-step explanation:
The y intercept is where it crosses the y axis
The y intercepts is -2
We need to determine the slope, by using to points on the line
(0,-2) and (2,0)
m = (y2-y1)/(x2-x1)
= (0 --2)/(2-0)
= (0+2)/(2-0)
= 2/2
= 1
The equation for the line is
y = mx+b where m is the slope and b is the y intercept
y = 1x-2
