In order to find y and x intercepts, we first need to know does they mean...

**What is x intercept ?**

It can be represented as point of a line intercepting x axis, if any point is to intercept x axis it's vertical position(y) has to be 0.

**What is y intercept ?**

if any point is to intercept y axis it's horizontal position(x) needs be 0.

**We can determine x intercept by setting y = 0**

**and y intercept by setting x = 0.**

so, for the line `-2x+5y=20`

1) Y intercept (x = 0) is

`-2(0) +5y =20`

=> `5y= 20`

=>` y=4`

` `

`-2x+5(0) =20`

=> `-2x= 20`

=>` x = -10`

so `x= -10 ,y =4` are the intercepts and is plotted with a dot in the graph below
