To find the y-intercept of a line, substitute the values of x and y coordinates into an equation representing the line. Set x to 0, then solve for y. If the equation is already in the slope-intercept form of y = mx + b, ... More »

Finding the x- and y-intercepts of a linear equation can be done in several ways, but one of the easiest is the substitution method. By substituting 0 for the values of x and y in the equation, each intercept can be loca... More »

The y-intercept is the point where a curve or a function intersects the y-axis. For a Cartesian plane, this refers to the point where x = 0. More »

The slope and the y-intercept of a line can be found graphically and mathematically. Use the slope equation and the slope intercept equation to find both variables mathematically, or view the graph of the line to determi... More »

According to South Eastern Louisiana University, to solve for the x and y intercepts in a linear equation of the form y = mx + b, set one of the variables, either x or y depending on the desired intercept, equal to zero,... More »

The linear rule is the idea that any point in a function falls on the same line, and writing an equation with the linear rule only requires knowledge of the function and y-intercept of the function. If two points on the ... More »
