Graph the solution to the system of inequalities
im trying to get a braph which shows

y>7x-4
y>=-2x-5

but because there is no equals sign it wont let me do it. Which calculator do i use for these types of equations, and will it show me the coordinates also??

Thanks

Re: Graph the solution to the system of inequalities
Use the Inequality Graphing in Two Variables Calculator.

Enter: y>7x-4&&y>=-2x-5

and you will get the graph plus the points of intersection.

There is a key on the keypad, "And", which translates to the double ampersand (&&), so you could alternatively type that key instead of the two ampersand keys.
