3y=4x-27
y=4/3x-9
That’s how you do the equation
For any circle with Cartesian equation

,
we have that the centre of the circle is

, and the radius of the circle is

.
So in the case that

,
we essentially have that

.
So the centre of the circle is

, and the radius is

.
Answer:
12 stores
Step-by-step explanation:
180 * 1/15 = 180/15 = 12
Answer:
-3
Step-by-step explanation:
Here is a different example.
'm' is the gradient (or slope). We measure the difference between the two x values and two y values to see how each of them changed respectively. We know m = rise/run so we can put in our slope (7) and points to find t.

The answer is either: (im making you choose)
-100
or
100
You multiply -10 by itself to get the correct answer
Dont forget about the signs
