- Solving systems of equations by graphing.
Step-by-step explanation:
The intersection point of the 2 lines would be the solution set to the systems of equations.
If the lines are parallel, they will have no solution.
If the lines are the same, they will have infinite amount of solutions.
According to the graph, it is the same line, so we have an infinite amount of solutions.
A) x + y = 2
B) x * y = -8
B) y = -8 / x we can substitute this into equation A
A) x + -8 /x = 2 multiplying both sides by "x"
A) x² -8 = 2x
x² +2x -8 = 0
(x + 4) * (x -2)
The 2 numbers are -4 and 2
