Question

How do you graph `x-1=y` using the intercepts?

Answer 1

`"see explanation"`

Explanation:

`"find the intercepts as follows"`

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

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

`x=0to0-1=yrArry=-1larrcolor(red)" y-intercept"`

`y=0tox-1=0rArrx=1larrcolor(red)" x-intercept"`

`"plot "(0,-1),(1,0)`

`"and draw a straight line through them"`
