Answer:
We can use number lines for adding as well as subtracting integers. For doing this:
1. First mark the first integer on the number line.
2. Now to add a positive integer to this number, move to the right on the number line from this number.
3. In case you have to add a negative integer, move to the left on the number line from this number.
4. Subtracting an integer means adding its opposite and hence, if you have to subtract a positive integer from this number, move to the left on the number line from this number.
5. But if you have to subtract a negative integer from this number, move to the right on the number line from this number.

Answer: slope, m = -1/2(coefficient of x in the equation
Step-by-step explanation:
y=-1/2x+4
We will compare the equation with the slope intercept equation ,
y = mx + c
Where y is the dependent variable
m is the slope
x is the independent variable
c is the intercept. This is where the line on the graph cuts the y axis
For y=-1/2x+4,
the intercept ,c is 4
Slope = m =-1/2
-1/2 is a negative slope because negative sign. This means the plotted line moves from up to down
The factors are all the possible things you would multiply to get the number. So finding the 2 middle numbers, in this case is 21 and 28 and multiplying them, you get 588. If you're not sure if that's right, take the number on the left or right of the 2 middle numbers, 14 and 42. The product of these 2 numbers are also 588. So your number is 588.
Let the lengths of EH and FG = x
Let the lengths of EF and HG = x-5
Solve,
X + X + (X-5) + (X-5) = 48
4X - 10 = 48
4X = 58
X = 14.5
EH= 14.5
FG = 14.5
EF = 9.5
HG = 9.5
