How To Find X Intercepts?

How do you find the x intercept of an equation?

To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’.

To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’.

How do I find the x intercepts of a parabola?

To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form). In this case, we end up with the square root of a negative number, so there are no x-intercepts.

How do you find the x intercept in a table?

Find the Initial Value and X Intercept from a Table –

How do you find the x intercept of a graph?

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.
