### What is Meant by Graphing Equations?

In Maths, a graph is a picture which is formed by plotting all the points of the given equation. If the equation contains only one variable, then the graph should be on the number line. If the equation contains two variables, say x and y, then the graph is on the coordinate plane. In case, if the equation has three variables, then the points should be plotted on the three-dimensional coordinate plane. If the given equation is linear, then the graph can be plotted by finding the two coordinate points such as (x1, y1) and (x2, y2).

For example, assume the linear equation, y=3x+1

From the given linear equation, we can say that the y-intercept is 1 and the slope value is 3. If we substitute y= 1 in the equation, we get the x-value as 0. So, the coordinate point is (0, 1). Now, graph the point (0, 1) in the coordinate plane. If x = 1, then the y-coordinate is 4. Hence, the second coordinate is (1, 4) and plot the point in the plane. Finally, draw the line that connects two points.
