x = -9
-3x when x is 3 would be -3(3) = -9
1/19 and then to draw a green marble would have to be 1/18 so I hope that helps
Color 2/8 of grid in green, 1/8 grid in red and 1/8 grid in blue
Step-by-step explanation:
find slope first
38-8/-14-(-20) = 5
y = 5x + b
find y intercept by sub in any set value show as long as they are belongs together
8 = 5(-20) + b
8 = -100 + b
108 = b
y = 5x + 108
