Chapter 3: Q. 69 (page 253)

Explain how would you choose three $x$ values to make a table to graph the line
$y = \frac{1}{5} x - 2$

Short Answer

Expert verified

We always prefer only those integers x-values which can give integer values of y-values, because it is easy to locate integer values.

The table is

$x$	$y$
$- 5$	$- 3$
$0$	$- 2$
$5$	$- 1$

The graph is

Step by step solution

Step 1. Given information

The equation of a line is

$y = \frac{1}{5} x - 2$

Making a table of three x values

We can select any random values of $x -$ values, but we should prefer only those integers $x -$ values that give integers $y -$ values.

So, $x = - 5, x = 0, x = 5$

$x$	$y = \frac{1}{5} x - 2$
$- 5$	$- 3$
$0$	$- 2$
$5$	$- 1$

Step 3. Sketching the graph of a line

Locate points $(- 5, - 3), (0, - 2), (5, - 1)$ on the graph and then join them to get the equation of a line.
