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
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)
