Question

What is the y-intercept for the line `y = 3x +5`?

Answer 1

`"y-intercept "=5`

Explanation:

`"to find the intercepts, that is where the line 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+5=5larrcolor(red)"y-intercept"`

`y=0rArr3x+5=0rArrx=-5/3larrcolor(red)"x-intercept"`
