In summary, intercepts are the points at which a graph intersects the x and y axes, also known as the x-intercept and y-intercept. Finding intercepts is important because it helps us understand the behavior of a linear equation or graph and can provide valuable information about the relationship between two variables. The steps for finding intercepts include setting one variable to 0, solving for the other variable, and repeating for the other variable before writing the coordinates as (x, y). Intercepts can be negative, meaning the graph or equation crosses the x or y axis at a negative value. In real-life situations, intercepts can be useful for calculating break-even points in business, determining the maximum and minimum values of a function, and analyzing

For the first one, we are told the $x$-intercept is at $-1$, this means the point $(-1,0)$ is on the line. Likewise, we are told the $y$-intercept is at $2$, this means the point $(0,2)$ is on the line. Plot those two points, then draw the line that contains those two points.

Can you proceed with the second problem?
 

FAQ: Finding Intercepts: Simple Steps to Refresh Your Memory

What are intercepts?

Intercepts are the points at which a graph intersects the x and y axes. They are also referred to as the x-intercept and y-intercept, respectively.

Why is finding intercepts important?

Finding intercepts helps us understand the behavior of a linear equation or graph, and can provide valuable information about the relationship between two variables.

What are the steps for finding intercepts?

Step 1: Set one of the variables (either x or y) to 0.
Step 2: Solve for the other variable.
Step 3: Repeat steps 1 and 2 for the other variable.
Step 4: Write the coordinates of the intercept as (x, y).

Can intercepts be negative?

Yes, intercepts can be negative. It simply means that the graph or equation crosses the x or y axis at a negative value on that axis.

How can finding intercepts be useful in real life situations?

Intercepts can be useful in various real-life situations, such as calculating break-even points in business, determining the maximum and minimum values of a function, and analyzing data in scientific experiments.
