Chapter 0.7, Problem 28E

To determine

To graph 4 points that satisfy the given function

Explanation of Solution

Given information: the function is,

  $y=1+x$

Graph:

  

Calculation:

For the point 1, substituting $x=0$

Hence,

  $y=1+0$

On solving,

  $y=1$

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

For the point 2, substituting $x=1$

Hence,

  $y=1+1$

On solving,

  $y=2$

Hence, co-ordinates of point1 are $(1,2)$

For the point 3, substituting $x=2$

Hence,

  $y=1+2$

On solving,

  $y=3$

Hence, co-ordinates of point1 are $(2,3)$

For the point 2, substituting $x=4$

Hence,

  $y=1+4$

On solving,

  $y=5$

Hence, co-ordinates of point1 are $(4,5)$

Hence, the four points are,

(0,1), (1,2), (2,3), (4,5)
