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.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
