baherus [9]

Answer:

There are 150 marbles.

30 % × 150 = 0.30 × 150 = 45

The number of blue or green marbles is 45.

Aneli [31]

Answer:

y = 5/8x - 3

Step-by-step explanation:

(8,2) and (-8,-8)

m=(y2-y1)/(x2-x1)

m = ( -8 -2)/ (-8 - 8)

m = (-10)/(-16)

m = 5/8

y - y1 = m(x - x1)

y - 2 = 5/8(x - 8)

y - 2 = 5/8x - 5

y = 5/8x - 3
