The y-intercept is the point at which the line crosses the y-axis; the value of x must be 0 at the y-intercept, because the y-axis is stationed at x = 0 on the graph. Consequently, to find the y-intercept, substitute 0 for x in your equation and calculate y. For equations of ...

The slope-intercept formula can also serve to change an equation into a graph. Simply follow the reverse instructions to do this: Plot the y-intercept as one point, and use the m value to draw a second point on your graph. Connect the two points to create the line. References Purple Ma...
Let us solve this system of equations by graphing. Here we can see the graphs of these two equations: The solution to this system is the point (0,2) As expected, the graphs of these two equations are straight lines, and those lines intersect at the point (0,2). So, the solution of...
One of the easiest ways to determine the linear equation of a graphed line is to use the slope-intercept formula. The slope-formula is y = mx + b, where x and y are coordinates of a point on a line, b is the y-intercept and m is the slope. The first step
