Question

How do you graph `y=3x+7` using intercepts?

Answer 1

`"see explanation"`

Explanation:

`"to find the intercepts"`

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

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

`x=0toy=0+7toy=7larrcolor(red)" y-intercept"`

`y=0to3x+7=0tox=-7/3larrcolor(red)" x-intercept"`

`"plot the points " (0,7),(-7/3,0)" and draw a straight line"`
`"through them"`
graph{3x+7 [-20, 20, -10, 10]}
