Answer:
5
Step-by-step explanation:
slope = 
The second y point is 16 and the first is -4, so:
(16) - (-4)
Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:
(-7) - (-3)
(-7) + (3)
Now solve both of them:
16 + 4 = 20
(-7) + 3 = -4
Remember, the slope formula is y over x, so we still need to put it into the fraction form:

You can reduce this to
, or 5.
Step-by-step explanation:
You need to find six combinations of a and b such that a² + b² = 7.
a = 1, b = √6
a = √2, b = √5
a = √3, b = 2
a = 2, b = √3
a = √5, b = √2
a = √6, b = 1
8 blocks because you multiply 20 by 2/5, then you get 4 multiplied by 2 and you get 8 blocks.
