Write the each equation in slope-intercept form y = mx + b.
-----------------------> (Equation 1)
-----------------------> (Equation 2)
Graph the equations and find the intersection point.
The graphs appear to intersect at (0, –4).
Check:
To check the solution by substituting the coordinates in each equation.
Substitute (0, –4) in equation 1.
(Apply zero product property: )
(Apply additive identity property: 0 – 4 = –4)
The statement is true.
Substitute (0, –4) in equation 2.
(Apply zero product property: )
(Apply additive identity property: 0 – 4 = –4)
The statement is true.
The solution of the system is (0, –4).
