Answer:
the d is right one look this img
The dance would /cost/ the school 50 dollars, making the profit -50. The dance tickets make 300, and the DJ takes away 250, making a 50 profit. However, the decorations cost 100, taking away that from 50, making -50.
(0,0),(2,16)
slope = (16 - 0) / (2 - 0) = 16/2 = 8
y = mx + b
slope(m) = 8
and since the line goes thru the origin, the y int is 0
in y = mx + b form, the slope is in the m position and the y int is n the b position....so ur equation is :
y = 8x + 0 which can be written as y = 8x <==
