Question

Find the decreasing functions and arrange them in order from least to greatest y-intercept. y = 2.5x + 10 y = -0.5x + 0.5 y = -4.5x + 3 y = -0.5x − 5 y = -2x + 7 y = -5x − 12

Answer 1

Y = 2.5x + 10 (Increasing)
y= -0.5x + 0.5 (Decreasing)
y = -4.5x + 3 (Decreasing)
y = -0.5x − 5 (Decreasing)
y = -2x + 7 (Decreasing)
y = -5x − 12 (Decreasing)

1)y = -5x − 12
2)y = -0.5x − 5
3)y= -0.5x + 0.5
4)y = -4.5x + 3
5)y = -2x + 7

6)y = 2.5x + 10 (increasing)

Decreasing/increasing = slope mx

y int = b (from mx + b)
