Answer

The \( x \)-intercept is \( (-3, 0) \) and the \( y \)-intercept is \( (0, 12) \).

Solution

To determine the \( x \)-intercept and \( y \)-intercept of the linear function \( y = 4x + 12 \), follow these steps: ### 1. Finding the \( y \)-Intercept The \( y \)-intercept occurs where \( x = 0 \). \[ y = 4(0) + 12 = 12 \] **\( y \)-Intercept:** \( (0, 12) \) ### 2. Finding the \( x \)-Intercept The \( x \)-intercept occurs where \( y = 0 \). \[ 0 = 4x + 12 \\ 4x = -12 \\ x = -3 \] **\( x \)-Intercept:** \( (-3, 0) \) ### Summary of Intercepts - **\( x \)-Intercept:** \( (-3, 0) \) - **\( y \)-Intercept:** \( (0, 12) \) ### Matching with the Provided Options - **Option A:** \( x \)-intercept \( (-3, 0) \) — **Partially Correct** - **Option B:** Incorrect assignments - **Option C:** Incorrect \( x \)-intercept - **Option D:** Incorrect \( x \)- and \( y \)-intercepts **Therefore, the correct intercepts are:** - **\( x \)-intercept:** \( (-3, 0) \) - **\( y \)-intercept:** \( (0, 12) \) Answer: The graph has an x-intercept at (–3 , 0) and a y-intercept at (0, 12).

Let's break down the function \( y = 4x + 12 \) to find the intercepts! To find the \( y \)-intercept, we set \( x = 0 \). So, \( y = 4(0) + 12 = 12 \). Thus, the \( y \)-intercept is \( (0, 12) \). Now, for the \( x \)-intercept, we set \( y = 0 \): \[ 0 = 4x + 12 \] Solving this gives \( 4x = -12 \) or \( x = -3 \). Hence, the \( x \)-intercept is \( (-3, 0) \)! The correct answer from the options provided is: \( x \)-intercept \( (-3, 0) \) and \( y \)-intercept \( (0, 12) \). Now, ready for some math fun? Did you know that linear equations trace straight lines on the graph? You could literally draw a line from the \( y \)-intercept to the \( x \)-intercept to illustrate how the function behaves between these points. It visually represents the relationship between \( x \) and \( y \)! Also, don’t shy away from experimenting with other values of \( x \) and \( y \)! Create a table of values and plot a few points. You could find that as \( x \) increases, \( y \) rises sharply because of that steep slope of 4! This way, you can get a better hands-on understanding of the linear relationship. Happy graphing!
