To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept. Just look on the graph for the point where the line crosses the x-axis, which is the horizontal axis. That point is the x intercept.

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Basic Graphing Functions To find the Y-intercept of a graph that has been drawn: Press "2nd," then "TRACE" to go to the "CALCULATE" window. Highlight "value" and press "ENTER." At the bottom of the screen that appears, enter "0" after "X=." The result will be the Y-intercept and associated X-coordinate.

To find the y-intercept(s) (the point where the graph crosses the y-axis), substitute in 0 for x and solve for y or f(x). To find the x-intercept(s) (the point where the graph crosses the x-axis â€“ also known as zeros), substitute in 0 for y and solve for x.

All logarithmic functions will have a vertical asymptote and pass through the point at distance 1 from the vertical asymptote in the direction it opens up. This point will always be the x intercept. To find it, we can set y equal to 0 and solve for x. Let's look at the graph of f(x) = ln(5-x).

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Rewrite in slope-intercept form. Subtract 3x 3 x from both sides of the equation. Divide each term by 4 4 and simplify.

Using polynomial division, divide the numerator by the denominator to determine the line of the slant asymptote. To find x and y intercepts, set each variable equal to zero and solve in turn. Based on information gained so far, select x values and determine y values to create a chart of points to plot.

To find the x-intercepts algebraically, we let y = 0 in the equation and then solve for values of x. In the same manner, to find for y-intercepts algebraically, we let x = 0 in the equation and then solve for y.

The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x at which y=0 . There may be zero, one, or two x -intercepts.
