Find the Equation of a Line Given That You Know Its Slope and Y-Intercept The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know the slope (m) any y-intercept (b) of a line, this page will show you how to find the equation of the line. A quadratic function is a second degree equation – that is, 2 is the highest power of the independent variable. Written in standard form, the equation y = ax 2 + bx + c (a 0) represents quadratic functions. When graphed in the coordinate plane, a quadratic function takes the shape of a parabola. To see a parabola in the real world, throw a ball.

In this activity, the learner will analyze graphs of quadratic equations (parabolas) to determine which of three statements is incorrect. Graph y = -3. Solution . The equation y = -3 or equivalently y = 0x -3, always gives the same y -value, - 3, for any value of x . Therefore, no value of x will make y = 0, so the graph has no x -intercept. The graph of such an equation is a horizontal line parallel to the x -axis. In this case the y -intercept is - 3, as shown in Figure 8.

Finding the y intercept of a parabola is a key of working with quadratic equations. These are mathematical functions where an x variables is squared, or taken to the second power like this: x2. When these functions are graphed, they create a parabola which looks like a curved "U" shape on the graph.
