To graph an equation, you can follow these steps:
1. Identify the variables in the equation. Typically, the variables will be represented by x and y.
2. Choose values for one of the variables (usually x) and solve for the other variable (y). This will give you specific points on the graph.
3. Plot the points on a coordinate plane.
4. Connect the points with a straight line to visualize the graph of the equation.
Here is a quick check question:
Graph the equation y = 2x + 3.
To graph this equation, you can choose different values for x and find the corresponding y values. For example, if x = 0, then y = 3. If x = 1, then y = 5. If x = -1, then y = 1.
Plot these points on a coordinate plane and connect them with a straight line. The graph of the equation y = 2x + 3 will be a straight line passing through the points (0,3), (1,5), and (-1,1).
