How do you find the intercepts of an equation?

How do you find the intercepts of an equation?

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. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x – 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

How do you describe what intercepts mean?

An intercept of any function is a point where the graph of the function crosses, or intercepts, the x-axis or y-axis.

What is the y-intercept of the line Khan Academy?

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.

How to interpret the intercept term in a GLM?

The intercept term is the intercept in the linear part of the GLM equation, so your model for the mean is E[Y] = g − 1(Xβ), where g is your link function and Xβ is your linear model. This linear model contains an “intercept term”, i.e.:

How to find the intercepts of an equation?

Finding Intercepts From an Equation. X Intercept: where the graph of an equation crosses the x-axis. Y Intercept: where the graph of an equation crosses the y-axis. To find the intercepts: When you want the x intercepts (x,0): Set y=0 then solve for x. When you want the y intercepts (0,y):

When to use the intercept in a model?

If you have dummy variables in your model, though, the intercept has more meaning. Dummy coded variables have values of 0 for the reference group and 1 for the comparison group. Since the intercept is the expected mean value when X=0, it is the mean value only for the reference group (when all other X=0).

When to use a non IDMS traceable equation for GFR?

Because creatinine results that are calibrated to IDMS may differ by 5 to 30% compared to uncalibrated results, 1 use of a non-IDMS traceable equation with IDMS calibrated results will yield an inaccurate eGFR. Therefore, all laboratories should use an IDMS traceable equation when estimating and reporting GFR.
