Question

find the distance between the points (-7.5, 8.9) and (3, 8.9). units submit

Explanation:

Step1: Identify the formula for distance between two points with same y - coordinate

When two points \((x_1,y_1)\) and \((x_2,y_2)\) have \(y_1 = y_2\), the distance \(d=\vert x_2 - x_1\vert\). Here, \(x_1=-7.5\), \(x_2 = 3\), \(y_1=8.9\), \(y_2 = 8.9\).

Step2: Calculate the distance

Substitute the values into the formula: \(d=\vert3-(-7.5)\vert=\vert3 + 7.5\vert\).
Since \(3+7.5=10.5\), and \(\vert10.5\vert=10.5\).

Answer:

\(10.5\)
