Suppose the constant rate of change of y with respect to z i

Suppose the constant rate of change of y with respect to z is 6.1, and the value of y is 8 when the value of z is 7. a. What is the value of y when the value of z is -3? Preview b. What is the value of y when the value of z is 9? Preview c. What is the value of z when the value of y is 1? Preview

Solution

y= mx +b

8=6.1(7)+b

b=8 -42.7 = -34.7

y= 6.1x -34.7

a.x=-3

y= 6.1(-3)-34.7=-53

b. x=9

y= 6.1(9)-34.7= 20.2

c.y=1

1=6.1x-34.7

x=5.9
