In the following exercises, graph using the intercepts.
$2 x - 5 y = - 20$ .

Short Answer

Expert verified

The graph is as follows,

Step by step solution

Step 1. Given Information.

The equation is $2 x - 5 y = - 20$ .

Find the intercepts.
Make the table for graph.
Draw the graph.

Step 2. Explanation.

Find the intercept and third point.

To find y-intercept, substitute $x = 0$ in the equation.

$2 x - 5 y = - 20 2 (0) - 5 y = - 20 - 5 y = - 20 y = 4$

To find x-intercept, substitute $y = 0$ in the equation.

$2 x - 5 y = - 20 2 x - 5 (0) = - 20 2 x = - 20 x = - 10$

To find third point consider x be any number.

Let $x = 4$ .

$2 x - 5 y = - 20 2 (4) - 5 y = - 20 8 - 5 y = - 20 - 5 y = - 28 y = \frac{28}{5}$

The table is as follows,

x	y	$(x, y)$
0	4	$(0, 4)$
-10	0	$(- 10, 0)$
4	$\frac{28}{5}$	$(4, \frac{28}{5})$

Step 3. Draw the graph.

The graph is as follows,
