Q. The equation y=23(x−8) is graphed in the xy-plane. Which of the following equations will have a graph that is parallel to the graph of the given equation and have an x intercept on the negative x-axis?Choose 1 answer:(A) y=23(x+8)(B) y=23x−8(C) y=−32(x+8)(D) y=−32x−8
Find equation with same slope: We need to find an equation with a slope that is the same as the slope of the given equation y=(23)(x−8) to ensure the graphs are parallel. The slope of the given equation is 23.
Analyze options: The x-intercept occurs when y=0. For the graph to have an x-intercept on the negative x-axis, the x-value at this intercept must be negative.
Option A: Let's analyze the options one by one to see which one satisfies both conditions:(A) y=(23)(x+8) - This equation has the same slope as the given equation, but the x-intercept would be at x=−8, which is on the negative x-axis. This is a potential correct answer.
Option B: (B) y=23x−8 - This equation has the same slope as the given equation, but the y-intercept is −8, not the x-intercept. We need to find the x-intercept by setting y=0 and solving for x: 0=23x−8⇒x=316, which is positive. So, this option does not satisfy the condition of having an x-intercept on the negative x-axis.
Option C: (C) y=−(32)(x+8) - This equation has a different slope (−32) from the given equation (23), so the graphs will not be parallel. This option is incorrect.
Option D: (D) y=−(32)x−8 - This equation also has a different slope (−32) from the given equation (23), so the graphs will not be parallel. This option is incorrect as well.
