Chapter 0.7, Problem 27E

To determine

To graph 4 points that satisfy the given function

Explanation of Solution

Given information: the function is,

  $y=2x$

Graph:

  

Calculation:

For the point 1, substituting $x=0$

Hence,

  $y=2(0)$

On solving,

  $y=0$

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

For the point 2, substituting $x=1$

Hence,

  $y=2(1)$

On solving,

  $y=2$

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

For the point 3, substituting $x=2$

Hence,

  $y=2(2)$

On solving,

  $y=4$

Hence, co-ordinates of point1 are $(2,4)$

For the point 2, substituting $x=4$

Hence,

  $y=2(4)$

On solving,

  $y=8$

Hence, co-ordinates of point1 are $(4,8)$

Hence, the four points are,

(0,0), (1,2), (2,4), (4,8)
