Answer:
1 ) y = 2x - 1
slope = 2
y intercept is (0,-1)
2) y = -1/2x + 5
slope = -0.5
y intercept = (0,5)
Step-by-step explanation:
18/2 = 9 Miles per hour for running
60/3 = 20 Miles per hour for biking
<span>a ³-2a² +5a
(2/3)^3 - 2(2/3)^2 + 5(2/3)
(8/27) - 2(4/9) + (10/3)
(8/27) - (8/9) + (10/3)
(8 - 24 + 90) / 27
(98 - 24) / 27
74 / 27
