The Correct Answer and Explanation is:

To graph the equation 3x+8y=243x + 8y = 243x+8y=24 using intercepts, we will find the x-intercept and y-intercept.

Step 1: Find the x-intercept.

The x-intercept occurs when y=0y = 0y=0. Substitute y=0y = 0y=0 into the equation:3x+8(0)=243x + 8(0) = 243x+8(0)=243x=243x = 243x=24x=243=8x = \frac{24}{3} = 8x=324​=8

So, the x-intercept is (8,0)(8, 0)(8,0).

Step 2: Find the y-intercept.

The y-intercept occurs when x=0x = 0x=0. Substitute x=0x = 0x=0 into the equation:3(0)+8y=243(0) + 8y = 243(0)+8y=248y=248y = 248y=24y=248=3y = \frac{24}{8} = 3y=824​=3

So, the y-intercept is (0,3)(0, 3)(0,3).

Step 3: Plotting the intercepts.

Now that we have the intercepts:

  • x-intercept: (8,0)(8, 0)(8,0)
  • y-intercept: (0,3)(0, 3)(0,3)

You can plot these two points on the graph:

  1. The point (8,0)(8, 0)(8,0) on the x-axis.
  2. The point (0,3)(0, 3)(0,3) on the y-axis.

Step 4: Draw the line.

Now, draw a straight line through these two points. This line represents the equation 3x+8y=243x + 8y = 243x+8y=24.

Conclusion:

  • The equation 3x+8y=243x + 8y = 243x+8y=24 is a straight line.
  • It intersects the x-axis at (8,0)(8, 0)(8,0) and the y-axis at (0,3)(0, 3)(0,3).
  • The graph of the line passes through these two points, and you can use these intercepts to sketch the function.
