what is the formula to find the x intercept?
300120
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x - 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

To find the y-intercept, calculate and , the average of the x- and y-values respectively. Then substitute these two values for x and y in the = b + a equation.

When there is no C value in the standard equation, it is understood to be C = 0 (has a Y intercept of 0), since . To solve quadratic equation (finding zeros aka X intercepts), first set the equation to zero () if not already set. Then you could factor if possible, or use the quadratic formula.

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.

X-intercept is the point where the line crosses the x-axis. Y-intercept is the point where the line crosses the y-axis. FINDING INTERCEPTS ALGEBRAICALLY: TO FIND THE X-INTERCEPT: LET Y = 0 AND SOLVE FOR X. TO FIND THE Y-INTERCEPT: LET X = 0 AND SOLVE FOR Y.

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.

We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.
