See explanation.
Explanation:
To solve the system of equations by graphing you have to plot the two graphs on a single coordinate plane and see if the graphs:
-
have no common points (are two parallel disjoint lines)
-
have infinitely many common points (two functions are the same line)
-
have exactly one common point
Here we can see:
graph{(2x+y-5)(3x-y-10)=0 [-10, 10, -5, 5]}
As we can see the graphs intersect in
