Question

How do you graph using the intercepts for `6x - y = 4`?

Answer 1

`y=6x-4`
`x_1=1rArry_1=6*1-4=2`
`x_2=2rArry_2=6*2-4=8`
graph{y=6x-4 [-10, 10, -5, 5]}

Answer 2

`"see explanation"`

Explanation:

`"to find the intercepts, that is where the graph crosses"`
`"the x and y axes"`

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

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

`x=0rArr0-y=4rArry=-4larrcolor(red)"y-intercept"`

`y=0rArr6x-0=4rArrx=4/6=2/3larrcolor(red)"x-intercept"`

`"plot the points "(0,-4)" and "(2/3,0)`

`"and draw a straight line through them for graph"`
graph{(y-6x+4)((x-0)^2+(y+4)^2-0.04)((x-2/3)^2+(y-0)^2-0.04)=0 [-14.24, 14.23, -7.12, 7.12]}
