Bruce drives his car for his job. the equation r=0.575m+42 models the relation between the amount in dollars. r, that he is reimbursed and the number of miles, m, he drives in one day. interpret the slope of the equation.

The slope, 0.575, means that the total amount Bruce is reimbursed in one day increases by 0.575 of a dollar for each mile he drives on that day.

Step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

the radius is 2 times the diameter.
