How to find the x-intercept of a function or equation requires setting the value of y to zero and calculating the answer(s) for x. The x-intercept formula for a linear equation when in the form Ax + By = C, is {eq}x = \frac{C}{A} {/eq} Or, when written in slope-intercept...
If a straight line intersects the X-axis at (2,0), the x-intercept will be 2. How to Find the X Intercept for Linear Data in Excel Consider a linear equation (y = 3x – 7). To find the value of X when y = 0: Select C12 >> use the following formula >> press Enter. =...
More specifically, the x-intercept is the point at which a graph crosses the x-axis, and the y-intercept is the point at which a graph crosses the y-axis. Finding the x- and y-intercepts may be done either graphically or algebraically. Functions and equations may either be linear or ...
The universal formula for every straight line, a linear equation, is: y = mx + b Where: m = the slope of the line (its steepness). The slope is found by dividing the change in y-value by the change in x-value, b = the y-intercept, x = the x-value. You will often need...
Linear FunctionsLinear functions are straight lines. This makes them very easy to graph, so long as you know how to determine the slope and y-intercept from the formula of the function. Linear functions are polynomials, but they can only have a degree of either 0 or 1. Th...
