Answer:
20% tip
Step-by-step explanation:
4/20 = 0.2
Convert to a percentage:
0.2*100 = 20%
20%
Divide 4 (tip) by 20 (total bill) and you get 20 percent.
I believe the answer is -0. 2
0 =-4.5X +49.5
x = 11
x1 y1 x2 y2
1 45 3 36
(Y2-Y1) (36)-(45)= -9 ΔY -9
(X2-X1) (3)-(1)= 2 ΔX 2
slope= -4 1/2
B= 49 1/2
Y =-4.5X +49.5
