how do you write an eqaution that relates to the cordinates on a graph
Gee, I do not know where to start.
There are lots of shapes that have equations on a graph.
Like a c1rcle might be x^2 + y^2 = 9
That would have center at (0,0) and radius of 3
You can graph just about any equation on the xy-plane. You need to know the values for the x and y coordinates in the form (x,y).
The easiest way to graph any equation in algebra is to make a table. Basically, you will plug a bunch of numbers for x (say about 3 numbers) and find out what the corresponding y values are to complete the ordered pair. The ordered pair is a point in the form (x,y) where x represents the x-axis and y represents the y-xis.
Once you do, you can plot that (x,y) pair on the coordinate plane (also called the xy-plane), secure in the knowledge that it falls on the graph.
Here are the steps to graph a linear equation:
1-Solve for y.
2-Plug in a few values for x and record the resulting y values to make points in the (x,y) form.
3-Plot the points on the coordinate plane and connect them to form the graph.
Keep in mind that the steps above only apply for linear equations (equations that form straight lines).
Is this clear?

To write an equation that relates to the coordinates on a graph, you need to determine the pattern or relationship between the x and y values. There are different types of equations for different types of graphs. Here are a few examples:
1. Linear Equation:
If the points on the graph lie on a straight line, you can write an equation in the form y = mx + b. Here, m is the slope of the line (indicating how steep it is), and b is the y-intercept (where the line crosses the y-axis). To find the equation, you need to calculate the values of m and b based on the given points on the graph.
2. Quadratic Equation:
If the graph is a parabolic shape, you can write an equation in the form y = ax^2 + bx + c. Here, a, b, and c are coefficients that determine the shape of the parabola. To find the equation, you need to substitute the coordinates of the given points into the equation and solve the resulting system of equations.
3. Exponential Equation:
If the graph shows exponential growth or decay, you can write an equation in the form y = ab^x. Here, a is the initial value, b is the base, and x represents the exponent. To find the equation, you need to substitute the coordinates of the given points into the equation and solve for the values of a and b.
These are just a few examples, and there are many other types of equations based on the nature of the graph. Identifying the pattern and understanding the relationship between the coordinates will guide you in selecting the appropriate equation to represent the graph accurately.
