Question 143688: Graph the line containing the given pair of points and find the slope.
(4,0), (-2, -3)
Find the slope of the line m = ??
Do I have to use 2 lines in the graph??
I do not understand. Help.

You can put this solution on YOUR website!
(4,0), (-2, -3)

m=+%28RISE%29%2F%28RUN%29+
m=%28-3-0%29%2F%28-2-4%29+=%28-3%29%2F-6+=1%2F2

To graph the line, all you need to do is plot the two points, and connect the dots!! In order to graph in algebra.com, I need to use the equation.
graph%28300%2C300%2C+-10%2C10%2C-10%2C10%2C+%281%2F2%29x-2%29

NO EXTRA CHARGE: I need to also find the y-intercept, which I figure is -2. This is what I get. Are you allowed to use a graphing calculator to check the answer?
