Question

What is the distance between E(5,1) and F(7,10) Round to the nearest tenth

Answer 1

Use the distance formula say F is x2, y2 and point E is x1,y1
Do the square root of (7-5)^2 + (10-1)^2 and you'll get the square root of 85 = 9.2 (rounded to nearest tenth)

Answer 2

$\bf \textit{distance between 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) E&({{ 5}}\quad ,&{{ 1}})\quad % (c,d) F&({{ 7}}\quad ,&{{ 10}}) \end{array}\qquad % distance value d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}$
