Question

plot the points (10, 0) and (-6, 0). click on the graph to plot a point. click a point to delete it. find the horizontal distance between the two points.

Explanation:

Step1: Recall distance formula for horizontal points

For two points $(x_1,y_1)$ and $(x_2,y_2)$ with $y_1 = y_2$, the horizontal distance $d$ is given by $d=\vert x_1 - x_2\vert$. Here, $x_1 = 10$, $x_2=-6$ and $y_1 = y_2=0$.

Step2: Calculate the difference

$d=\vert10-(-6)\vert=\vert10 + 6\vert$.

Step3: Simplify the absolute - value

$\vert10 + 6\vert=\vert16\vert=16$.

Answer:

16
