The two lines graphed on the coordinate grid each represent an equation.
Which ordered pair represents a solution to both equations?
a (-5, -1)
b (-1, -5)
c (1, 5)
d (-1, 5)
Graphed at
(-7,-2)
(5, -2)
(-7, -8)
(7, -9)
To find out which ordered pair represents a solution to both equations, you need to see if the point lies on both lines.
The two equations are represented by the two lines graphed on the coordinate grid. If the point lies on both lines, then it is a solution to both equations.
Looking at the points given:
a (-5, -1) - Does not lie on both lines
b (-1, -5) - Does not lie on both lines
c (1, 5) - Does not lie on both lines
d (-1, 5) - Lies on both lines
Therefore, the ordered pair (d) (-1, 5) represents a solution to both equations.
