Write an equation to match this graph.

y = x + 7

Step-by-step explanation:

This is a linear equation graph because the line is straight and it is going at a constant rate. You can just either add or subtract the dependent event or the y variable.  So I use the linear equation y = mx + b.

Use the y2 - y1 / x2 - x1 to find the slope. The slope is basically m.  You can use any coordinate for this.

I will use (2, 9) and (3,10) as the coordinates for an example.

So y2 = 10

y1 = 9

x2 = 3

x1 = 2

10 - 9 / 3 - 2 = 1/1 = 1

1 is the same thing as x.

So the slope is x.

Now in order to find b(or the whole number on the far right), you use one of the x and y coordinates.

For an example I will use (5, 12)

Now all I do is use the formula y = mx + b

y = 12

x = 5

m = 1.  M is the same thing as slope.

b is what I must find out.

So I write 12 = 1(5) + b

12 = 5 + b

Then you subtract 5 from 12

and you will get 7.

12 - 5 = 7

The b or the y intercept equals 7.

So the equation for this graph is y = x + 7

Simple bro! The hard part was the explanation.

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
