Question

1. what is the distance between point a(3,4) and point b(10,4)?

a) 4
b) 5
c) 6
d) 7

Explanation:

Step1: Use the distance formula for points with same y - coordinate

For two points \((x_1,y_1)\) and \((x_2,y_2)\), if \(y_1 = y_2\), the distance \(d=\vert x_2 - x_1\vert\). Here \(x_1 = 3,y_1 = 4,x_2=10,y_2 = 4\).

Step2: Calculate the distance

\(d=\vert10 - 3\vert=\vert7\vert = 7\)

Answer:

D. 7
