In y = mx + b...the slope is in the m position and the y intercept is in the b position.
y = -7x - 2
slope(m) = -7
y int (b) = -2...or (0,-2)

Firstly, to calculate a price you need to change the percentage into a decimal. You do this by dividing it by 100.
45 / 100 = 0.45,
The discount price will be 55% of the original price,
55 / 100 = 0.55,
19 * 0.55 = 10.45,
So the discound price will be $10.45
Hope this helps!
