Question

a. The graph of the relationship that passes through the poirt (9, - 21.6) and the change in y is always -4.9 times as large as the change in x . y=-4.9x+22.5 Preview b. A relationship where the constant rate of change of y with respect to z is 1/6 and passes through the point1 y-.16667x+216.84Preview c. The graph of the relationship between y and a that passes through the points (-8, 13) and (-11,-89) =7.3x+71.4 Preview Points possible: 1 Unlimited attempts Score on last attemnt: 07 Score in gradehook-07 License 13

Explanation / Answer

b) constant rate of change of y with respect to x = 1/6

passes through ( -3/5 , 2/11)

standard equation is given by

y = mx + b

plugging the values

2/11 = -3/5 (1/6) + b

2/11 + 3 / 30 = b

b = 31/110

hence, equation is

y = 1/6 x + 31/110

or

y = 0.1667x + 0.2818
