Answer:
Step-by-step explanation:
B = 2/5(A - 9)
(5/2)B = A - 9
A = 9 + (5/2)B
Sorry that's all i know
b 2/7
Because there is a 6/21 chance and 2/7=6/21
3 and 9
3 * 24 = 72
9 * 8 = 72
3 * 15 = 45
9 * 5 = 45
Vertical stretch of factor of 3
translated to the right 2
translated up 5
the slope would be the change in Y over the change in X,
-7-1= -8, 3-(-1)= 4, -8/4 or -2 is the slope
