Answer:
y+5 = 3/4(x+8)
Step-by-step explanation:
The point slope form of the equation of a line is
y - y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
The slope is 3/4 and the point is (-8,-5)
y - -5= 3/4( x - -8)
y+5 = 3/4(x+8)
First we divide it by 100 to get 1% of the original price, which is $0.295.
Then we multiply that by 22 to get 22% of the original price: $6.49.
The discount was $6.49, hope this helps!
If we let y = f(x), then it is just:
f(x) = -3x + 9
