Chapter 1: Q. 20 (page 24)

Find the intercepts and graph each equation by plotting points. Be sure to label the intercepts.
$5 x + 2 y = 10$ .

Short Answer

Expert verified

The intercepts are :

x-intercept is $(2, 0)$ and y-intercept is $(0, 5)$ .

Step by step solution

Given information:

Consider the equation,

$5 x + 2 y = 10$ .

To find the x-intercept:

Let $y = 0$ in the equation,

Then, $5 x + 2 脳 0 = 10$

$5 x = 10$

$\frac{5 x}{5} = \frac{10}{5}$

$x = 2$

$x - i n t e r c e p t i s (2, 0) .$

To find the y-intercept:

Let $x = 0$ in the equation,

Then, $5 脳 0 + 2 y = 10$

$2 y = 10$

$\frac{2 y}{2} = \frac{10}{2}$

$y = 5$

$y - i n t e r c e p t i s (0, 5)$ .

To draw the graph:

We can draw the graph of the equation $5 x + 2 y = 10$ by plotting the above intercepts and the points in the table below,

$x$	$y = \frac{10 - 5 x}{2}$	$(x, y)$
$- 2$	$10$	$(- 2, 10)$
$- 1$	$\frac{15}{2}$	$(- 1, \frac{15}{2})$
$1$	$\frac{5}{2}$	$(1, \frac{5}{2})$
$3$	$\frac{- 5}{2}$	$(3, \frac{- 5}{2})$
