Chapter 0, Problem 47PG

To determine

To graph 3 points

Answer to Problem 47PG

Points are:

x	2	4	6
y	-4	-3	-2

Explanation of Solution

Given information:

  $y=\frac{1}{2}x-5$

Calculation:

To find 3 points to graph the equation, put value of x to get y ,

x	2	4	6
y	-4	-3	-2

Putting x =2,

Substituting values,

  $y=\frac{1}{2}(2)-5$

Solving,

  $y=1-5$

So,

  $y=-4$

Putting x =2,

Substituting values,

  $y=\frac{1}{2}(4)-5$

Solving,

  $y=-3$

Putting x =2,

Substituting values,

  $y=\frac{1}{2}(6)-5$

Solving,

  $y=3-5$

So,

  $y=-2$
