How to find x intercept on a table

To find the x-intercept of a line of the form y = mx+b, substitute y = 0. Example: To calculate the x-intercept of any line for example the line y = 2x−4, put y = 0 in the equation of a line. Solution: 0 = 2x−4 4 = 2x 2 = x. So, the x-intercept of the line y=2x−4 is 2. Similarly, by substituting x = 0, we can find the y-intercept y = 2(0)−4 y= -4

How to find Y Intercept on a Graph or Table

Find the x-intercepts for the function: y = x 2 + 2 x – 8 Solution As before, let y = 0 and solve for x. This time, you have a quadratic equation to solve. 0 = x 2 + 2 x – 8 0 = ( x + 4) ( x – 2) x = − 4, 2 Answer: This function has two x-intercepts: –4
