So just divide 100 by 25 which equals 4 then divide 120 by 30 which also equals to 4 and if the rest equal 4 then its proportional (1)
And then same for 2 and 3 just divided the bottom by the top and if they all get the same answer they are proportion and if one is not the same then it’s not
For the grids if the dots are line diagonally straight and it starts at the 0 then it’s proportional if not then it’s not
Hope this helps :)
Answer:

Step-by-step explanation:
We want to write the equation of a line that passes through (5, 6) and (-1, 4).
First, let's find our slope. We can use the slope formula:

Let's let (5, 6) be (x₁, y₁) and let's let (-1, 4) be (x₂, y₂). So, our slope is:

Subtract:

Reduce:

So, our slope is 1/3.
Now, we can use the point-slope form, which is:

For consistency, let's let (5, 6) be (x₁, y₁). We will also substitute 1/3 for m. So:

Distribute:

Add 6 to both sides:

Add:

And we're done!
The step in this problem is do 1/4 + 1/3= ?
and see what you get
10 10 10 1 is 31 split into three tens and one one. I'm guessing this is what you meant.
Step-by-step explanation:
160 + Percentage increase =
160 + (4% × 160) =
160 + 4% × 160 =
104 ÷ 100 × 160 =
104 × 160 ÷ 100 =
