Answer:
(5,4) & (8,-10)
Step-by-step explanation:
First step:
You can use any number you want for b (I used 4)
Make x=0
Make y=0
Subtract 4 from both sides
Divide both sides by 
Second step:
In order to make a line perpendicular to another the slope of the second line will be the negative inverse of the first line. So 
will be 
for the second line.
Then you just need to repeat the process in first step to get the intercepts. (Again I used a random number like -10 for b)
You have 7 numbers, two numbers 4 , one 5, one 6 and three numbers 7.
From these 7 numbers you can create
phone numbers, but they are not all different.
If you have two numbers 4, then you have to divide obtained number by 2! (the number of all possible permutations of two numbers 4) and since you have three numbers 7 you should divide the obtained number by 3! (<span>the number of all possible <span>permutations of three numbers 7</span>). Then</span><span /><span>

Answer:
2
Step-by-step explanation:
The rate of change is just the slope, which is -6/-3 or 2.
You will find the length of all sides to be able to multiply length by width
8500-3000is 5500
So 10% of 5500is 550. (Assuming this is a a one time fee)
So add both together to get the remaining balance to break down into payments
6050 divided by 30=201.67
