Step-by-step explanation:
I would have 9 to graduate
(1, 1) and (4, -4)
Slope formula is : m = (y₂-y₁) / (x₂-x₁)
In this case :
x₁ = 1 ; x₂ = 4 ; y₁ = 1 ; y₂ = -4
Now that you know what variable counts as what, we simply just need to plug everything in.
m = (-4 - 1) / (4 - 1)
Simplify.
m = -5/3
Therefore, your slope is -5/3
~Hope I helped~ :)
I believe you would take 127.5 and divide it by 8.5, try that and see if that works, hope this helps!
It will be 1 of the 100block
5 of the tens block and 2 single
