1. The x-intercept coordinates are (x1,y1) = (-3,0).

The y-intercept coordinates are

(x2,y2) = (0,6).

The slope is

m = (y2-y1)/(x2-x1)

Do the calculations and see what you get.

2. After you have solved for m, write the equation on the form

y = m x + b

You can use that equation with either (x1,y1) or (x2,y2) to figure out what b is.

If you don't attempt these yourself you will not learn the subject. Let us know what you get if you want us to verify your answers.
