What is the x-intercept of the equation y = -3x + 8?

8
-8
-3
3

The correct answer is: 3

The x-intercept of an equation is the point where the graph crosses the x-axis. In order to find the x-intercept, we need to make y = 0. So, let y = 0 in the equation y = -3x + 8 0 = -3x + 8 Now we can solve for x: 3x = 8 x = 8/3 Therefore, the x-intercept is 8/3 or 2.67. Looking at the options, only option D, 3, is equivalent to 8/3. All the other options either have a wrong sign or a wrong value, making them incorrect answers for the x-intercept of y = -3x + 8.
