The y-intercept is where the parabola of a function crosses (or intercepts) the y axis. Another way to define the y-intercept is the value of y when x is equal to zero. Because the y intercept is a point on a graph, you'll usually write it in point/coordinateform. For example, l...
Y-Intercept The y-intercept is the point at which the line crosses the y-axis; the value of x must be 0 at the y-intercept, because the y-axis is stationed at x = 0 on the graph. Consequently, to find the y-intercept, substitute 0 for x in your equation and calculate y. For ...
I use the example below in my post abouthow to interpret regression p-values and coefficients. The graph displays a regression model that assesses the relationship between height and weight. For this post, I modified the y-axis scale to illustrate the y-intercept, but the overall results haven...
In summary, if you are interested in the two-intercept form of a line, you can use the given intercepts to determine the slope, and then use the slope-intercept form. Sep 1, 2017 #1 mathdad 1,283 1 Find an equation of the line whose x-intercept is -6 and ...
How to Determine End Behavior & Intercepts to Graph a Polynomial Function: Example 1 Graph the following function by determining the end behaviors and intercepts from the equation:f(x)=(x−2)2(x+1)(x+5). Step 1:Identify the x-intercept(s). ...
The slope-intercept formula can also serve to change an equation into a graph. Simply follow the reverse instructions to do this: Plot the y-intercept as one point, and use the m value to draw a second point on your graph. Connect the two points to create the line. ...
Go back to the graph. An equation is displayed in the chart area: y=-0.0001x+0.9016 This is the output: the x-intercept is0.9016(90.16%, when formatted as a percentage). Read More:How to Set Intercept Trendline in Excel Method 4 – Using the LINEST Function to Find the x-Intercept ...
A regression line generally shows the connection between some scatter data points from a dataset. The equation for a regression line is: y = mx + b m = Slope of the Regression Line. B = Y-Intercept. You can also use the following formula to find the slope of a regression line: This...
Now that we know the equation of each line, we can determine where the lines intersect by setting the equations equal to each other. 2x-8 = 4x-17 9 = 2x x = 9/2. This is the x coordinate of the point of intersection. To determine the y coordinate, plug x=9/2 into one of the...
