Question

plot the points (-1, -9) and (8, -9). click on the graph to plot a point. click a point to delete it. find the horizontal distance between the two points. answer attempt 1 out of 5 units submit answer

Explanation:

Step1: Identify x - coordinates

The x - coordinates of the two points are $x_1=-1$ and $x_2 = 8$.

Step2: Calculate horizontal distance

The horizontal distance $d$ between two points with the same y - coordinate is given by $d=\vert x_2 - x_1\vert$. Substitute $x_1=-1$ and $x_2 = 8$ into the formula: $d=\vert8-(-1)\vert=\vert8 + 1\vert=9$.

Answer:
