# What is the y intercept in geometry?

In geometry, the y intercept is the point where a line crosses the y-axis on a coordinate plane. The y intercept can be used to determine the equation of a line when one point on the line and the y intercept are known. In this blog post, we'll take a closer look at what the y intercept is and how to find it.

To better understand what the y intercept is, let's take a look at what it isn't. The y intercept is not the slope of a line, nor is it the x intercept. The slope of a line tells us how steep the line is, while the x intercept tells us where a line crosses the x-axis.

Now that we know what the y intercept isn't, let's take a look at what it is. As we mentioned before, the y intercept is the point where a line crosses the y-axis. To find the y intercept, we need to know two things:

1) The equation of the line

2) A point on the line

Once we have these two pieces of information, we can plug them into the equation below to find the y intercept:

### y = mx + b

m = slope of the line

x = x coordinate of the point on the line

y = y coordinate of thte point on thte line

b = y intercept

Let's look at an example to see how this works in practice. Suppose we have the following equation for a line:

### y = 2x - 5

And we also know that this line passes throught he point (3,1). Plugging these values into our equation above, we get:

### 1 = 2(3) - 5

### 1 = 6 - 5

### 1 = 1

Therefore, our y interecept is 1.
