Chapter 3: Q. 45 (page 252)

Graph the equation-x+4y=8using the intercepts.

Short Answer

Expert verified

The graph of the given equation is

.

Step by step solution

01

Given information

The equation is given as -x+4y=8for the graph.

02

Find the intercepts

Apply the definition of the intercepts to find the intercepts of the given equation.

  • The intercepts of the given equation are the points where the corresponding variables become zero.
  • Hence substitute the associated variables zero into the given equation to find the required intercepts.

-x+4y=8-x+4(0)=8-x=8x=-8-x+4y=8-0+4y=84y=8y=84y=2

03

Graph the given equation

The graph of the linear equation is a straight line that passes through its intercepts.

  • As obtained, the intercepts of the given equation are (-8,0) and (0,2).
  • Hence join the intercepts using a straight line to get the required graph of the equation.
