Question

How do you find the x and y intercepts for `y + 4x= 5`?

Answer 1

`"x-intercept "=5/4," y-intercept "=5`

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=0rArry+0=5rArry=5larrcolor(red)"y-intercept"`

`y=0rArr0+4x=5rArrx=5/4larrcolor(red)"x-intercept"`
graph{(y+4x-5)((x-0)^2+(y-5)^2-0.04)((x-5/4)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
