## How do you find an intercept on a graph?

Finding x-intercepts and y-intercepts

1. 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.
2. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
3. To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

## What is the cover up method in algebra?

The cover-up method simply removes one variable at a time, in order to solve for the other variable. The solutions are then the intercepts, since removing a variable, or “covering up” a variable, is the same thing as setting it equal to zero.

What is the meaning of intercept in graph?

The intercepts are the points on a graph at which the graph crosses the two axes (x-axis and y-axis). The point where the graph crosses the x-axis is called the x-coordinate and the point where the graph crosses the y-axis is called the y-coordinate.

How do you solve intercepts?

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.

### How do you do intercepts in math?

To find the x-intercept, substitute y = 0 and solve for x. To find the y-intercept, substitute x =0 and solve for y.

### How do you find the rise over run on a graph?

Rise over run formula, calculating by hand All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run).

How do you use the cover-up method for X and y intercept?

How do you use the cover-up method to solve for the x and y intercept? I suppose that “cover-up” is a friendlier term for “setting a variable equal to zero,” so if you are looking for the x -intercept of a line, then set y equal to zero, and for y -intercept, set x -equal to zero. 2x +3y = 12. To find the x -intercept, set y = 0.

How do you find the intercepts of a graph?

You can use the x – and y – intercepts as two of your three points. Find the intercepts, and then find a third point to ensure accuracy. Make sure the points line up—then draw the line. This method is often the quickest way to graph a line. Graph –x + 2y = 6 – x + 2 y = 6 using the intercepts.

#### What is the x-intercept of a line with the cover-up?

I suppose that “cover-up” is a friendlier term for “setting a variable equal to zero,” so if you are looking for the x -intercept of a line, then set y equal to zero, and for y -intercept, set x -equal to zero. 2x+3y = 12. To find the x -intercept, set y = 0. So, the x -intercept is 6. To find the y -intercept, set x = 0.

#### How do you find the x-intercept of a line?

I suppose that “cover-up” is a friendlier term for “setting a variable equal to zero,” so if you are looking for the x -intercept of a line, then set y equal to zero, and for y -intercept, set x -equal to zero. 2x +3y = 12. To find the x -intercept, set y = 0. So, the x -intercept is 6.
