If the equation is in standard form:ax+by=c then you just set x equal to 0 to find the y intercept and set y equal to 0 to find the x intercept. It makes sense, right. The y intercept is when the line crosses the y axis, so x will always be 0, so that is why we set x equal to 0.

The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. 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.

Step 2: Use the formula y = mx + b to determine the y-intercept, b. Replace x and y in the formula with the coordinates of one of the given points, and replace m with the calculated value, (2). Find the equation of the line whose graph contains the points (1,–2) and (6,5). The answer will look like y = mx + b.

To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation. To graph a line, find the intercepts, if they exist, and draw a straight line through them.

Basic Graphing Functions To find the Y-intercept of a graph that has been drawn: Press "2nd," then "TRACE" to go to the "CALCULATE" window. Highlight "value" and press "ENTER." At the bottom of the screen that appears, enter "0" after "X=." The result will be the Y-intercept and associated X-coordinate.

The x-intercepts are points where the graph of a function or an equation crosses or “touches” the x-axis of the Cartesian Plane. You may think of this as a point with y-value of zero. To find the x-intercepts of an equation, let y = 0 y = 0 y=0 then solve for x. In a point notation, it is written as (x,0).

The slope-intercept form of a linear equation is written as y = mx + b, where m is the slope and b is the value of y at the y-intercept, which can be written as (0, b). When you know the slope and the y-intercept of a line you can use the slope-intercept form to immediately write the equation of that line.
