1. the x-intercept of a line is -3. the y-intercept of the line is 6. what is the slope of the line?
2. what is the equation in slope-intercept form of the line described in Exercise 1?

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.
