3 times 219 is 657 so you need 6 hundred value blocks 5 ten value blocks and 7 one value blocks
The formula of a slope:
We have the points A(-7, a) and B(c, d).
Substitute:
Exception: c ≠ -7.

dddasssssssssssssssssssssssssssssssssssssss
Step-by-step explanation:
The correct answer is 1.4 or 1 4/10
I did this by turning 7/10 into a decimal which is 0.7.
Now I just add 0.7 + 0.7.
For that equation i got 1.4
This would equal 1 4/10
Okay, so since both y values share the same number, let's add both equations so the y values cancel out leaving us to solve for x.
10x+(-5x)=5x
7y+(-7y)=0
1+24=25
Now we have 5x=25
divide both sides by 5 and we have x=5
Now that we know x=5, we can plug it into one of the problems to find y.
Let's do 10(5) +7y=1
50+7y=1 subtract 5 and we get 7y=-49
divide -7 from both sides and we get y=-7
so there you have it x=5 and y=-7
