Chapter 0.7, Problem 30E

To determine

To graph 4 points that satisfy the given function

Explanation of Solution

Given information: the function is,

  $y=2-x$

Graph:

  

Calculation:

For the point 1, substituting $x=0$

Hence,

  $y=2-0$

On solving,

  $y=2$

Hence, co-ordinates of point 1 are $(0,2)$

For the point 2, substituting $x=1$

Hence,

  $y=2-1$

On solving,

  $y=1$

Hence, co-ordinates of point1 are $(1,1)$

For the point 3, substituting $x=2$

Hence,

  $y=2-2$

On solving,

  $y=0$

Hence, co-ordinates of point1 are $(2,0)$

For the point 2, substituting $x=3$

Hence,

  $y=2-3$

On solving,

  $y=-1$

Hence, co-ordinates of point1 are $(3,-1)$

Hence, the four points are,

(0,1), (1,1), (2,2), (3,-1)
