Chapter 9.10, Problem 19PSC

a

To determine

To find:The slope of line h

Answer to Problem 19PSC

The slope of line is $m=0.667$

Explanation of Solution

Given information:The following points are given on line h

  $(5,0)$ and $(11,4)$

Formula used:A slope of any line can be found by

  $m=\frac{y_2-y_1}{x_2-x_1}$

Where x and y are the coordinates of points one and two

Calculation:We find the slope of line h as

  $m=\frac{4-0}{11-5}$

Hence, we get

  $m=0.667$

b

To determine

To find:The value of $m\angle 1$ to the nearest integer

Answer to Problem 19PSC

The value of $m\angle 1=1$

Explanation of Solution

Given information:The following points are given on line h

  $(5,0)$ and $(11,4)$

Formula used:A slope of any line can be found by

  $m=\frac{y_2-y_1}{x_2-x_1}$

Where x and y are the coordinates of points one and two

Calculation:We find the value of $m\angle 1$

  $m\angle 1=\frac{4-0}{11-5}=\frac{4}{6}$

Hence, we get

  $m\angle 1=\frac{2}{3}=0.67$

Thus, rounding off to the nearest integer, we get

  $m\angle 1=1$
