Answer:

Step-by-step explanation:
One is asked to find the distance between two points on a coordinate plane. The easiest way to do so is to use the distance formula, this formula is the following:

Where (
) and (
) are the points which one needs to find the distance between. In this case, these points are as follows:


Substitute these points into the formula and solve for the distance between these points,


Simplify,

Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
3a + b = 21
5a + b = 35
Subtract the 2 equations:
=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0
=> The solution is y = 7x
9.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
5a + b = 17
10a + b = 22
Subtract the 2 equations:
=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12
=> The solution is y = x + 12

5/12lb of dog food in each container.
This seems like a division problem so you would take (5/4) and divide it by 3 to make 3 equal groups meaning 5/12lb would be in each container.
I hope this helps, good luck!
Answer:
c because if you subtract
Answer:
slope=1
Step-by-step explanation:
Formula for slope is m =
y2 - y1
/x2 - x1
you will then use 7-8/4-5
Then -1/-1 which will simplify to 1
