Question

How do you graph `2x+y=8` using intercepts?

Answer 1

see explanation.

Explanation:

To find the intercepts.

`• " let y = 0, in the equation, for x-intercept"`

`• " let x = 0, in the equation, for y-intercept"`

`y=0to2x+0=8rArrx=4larrcolor(red)" x-intercept"`

`x=0to0+y=8rArry=8larrcolor(red)"y-intercept"`

Plot the points (4 ,0) and (0 ,8) draw a straight line through them and you have the graph of 2x + y = 8
