Kids Definition y-intercept noun y-in·ter·cept ˈwī-ˈint-ər-ˌsept : the ordinate of a point where a line or curve intersects the y-axis compare x-intercept Love words? Need even more de
is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line. The variable "m" is commonly used to denote slope in equations of lines, such as y = mx + b, where "m" represents the slope and "b" represents the y-intercept...
We will need to find the slope and the y-intercept. Slope: in this case we don’t know two points, but we are given a rate in dollars for monthly use of the phone. Our units are dollars per month because slope is ΔyΔxΔyΔx, and y is in dollars and x is in months. The...
Since we are given only two coordinate points, you will need to frame the equation using these points and then find the intercepts.STEP 2: You can use the slope-intercept form to find the equation of the line. By the slope-intercept form, we refer to an equation of the form:...
Determine the slope and the y-intercept of the following function:f(x)=−x−6. Slope: The slope is defined as the average rate of change from one point to another. In a linear function, the slope is always constant. The slope can be determined using two points and the sl...
intersects the y-axis to find the intercept. Third, use the two values for the slope-intercept form to determine the equation of the line. Example: find the equation of the line from the graph on the right. First: using the two points (1, 5) and (2, 8), draw imaginary lines...
Thenthe point(2, −1)is also on this line. And with these three points, we can graph the line: When you have the equation of a straight line, you can always do quick and easy graphing by starting with they-intercept value, and then plotting other points by using the slope value. ...
Find the x and y intercepts of a line using our intercept calculator. Find the y-intercept using two points or from the equation of a line.

Complete the Graph for Example 2 using the X-Y Grid Layout below. Simply Plot the Two Intercept values onto a labelled X-Y Grid, and then connect them with a straight line with arrows on each end. Also write the Equation of the Line onto the Grid. ...
