Understanding the Concept of Intercepts
In mathematics, the intercepts of an equation are the points at which the graph of the equation intersects the x-axis and the y-axis. The x-intercept is the point at which the graph intersects the x-axis, and the y-intercept is the point at which the graph intersects the y-axis. In this article, we will focus on finding the x-intercept and the y-intercept for the given equation.
The Given Equation
The given equation is:
This is a linear equation in the form of y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 1/2 and the y-intercept is -3/2.
Finding the { x $}$-intercept
To find the x-intercept, we need to set y = 0 and solve for x. This is because the x-intercept is the point at which the graph intersects the x-axis, and at this point, the value of y is 0.
Setting y = 0, we get:
Multiplying both sides by 2, we get:
Adding 3 to both sides, we get:
Therefore, the x-intercept is (3, 0).
Finding the { y $}$-intercept
To find the y-intercept, we need to set x = 0 and solve for y. This is because the y-intercept is the point at which the graph intersects the y-axis, and at this point, the value of x is 0.
Setting x = 0, we get:
Simplifying, we get:
Therefore, the y-intercept is (0, -3/2).
Conclusion
In this article, we have found the x-intercept and the y-intercept for the given equation. The x-intercept is (3, 0) and the y-intercept is (0, -3/2). These intercepts are important because they provide information about the graph of the equation and can be used to solve problems involving the equation.
Example Problems
Problem 1

Subtracting 2 from both sides, we get:
Therefore, the x-intercept is (-2, 0).
To find the y-intercept, we set x = 0 and solve for y:
Simplifying, we get:
Therefore, the y-intercept is (0, 2/3).
Problem 2
Find the x-intercept and the y-intercept for the equation:
Solution
To find the x-intercept, we set y = 0 and solve for x:
Multiplying both sides by 4, we get:
Adding 1 to both sides, we get:
Therefore, the x-intercept is (1, 0).
To find the y-intercept, we set x = 0 and solve for y:
Simplifying, we get:
Therefore, the y-intercept is (0, -1/4).
