Here it is

#### Explanation:

Hopefully, you have already learnt the equation of a line which states that

*where m is the gradient (m = y/x) and c is the y-intercept. (and x and y the coordinates.)*

Now arranging your equation into above mentioned format;

#y = (-x)/-9 +( -45)/-9#

#y =1/9*x+5#

Now you from this equation you can see that

**SO OUR Y-INTERCEPT IS FOUND WHICH IS 5.**

Now for finding **x-intercept** then y coordinate must be equal to *ZERO.*

So we put the equation equal to ZERO, like this:

SO at -45 the line intersects the x-axis.

**SO OUR X-INTERCEPT EQUALS TO -45.**
