X-Intercept Formula
The formula of x-intercept for slope-intercept equation y = mx + c is given by,
x-intercept = -c/m
Thus, (-c/m, 0) is the coordinate of x-intercept.
Where,
- (0, c) is the y-intercept,
- m is the slope of the given line.
X and Y Intercept Formula
X and Y Intercept Formula as the name suggests, is the formula to calculate the intercept of a given straight line. An intercept is defined as the point at which the line or curve intersects the graph’s axis. The intercept of a line is the point at which it intersects the x-axis or the y-axis.
When an equation isn’t in the form y = mx + b, we determine the intercepts by substituting 0 as necessary and solving for the corresponding variable.
- To find the y-intercept, we set x = 0 and solve for y. This yields the point (0,y).
- To find the x-intercept, we set y = 0 and solve for x. This gives us the point (x,0).
