Answer:
The solutions for the equation are:
(4,-2) and (-16,-17)
Step-by-step explanation:
Given equation:
Given points:
(0,-5), (4,-2), (8,2), (-16,-17), (-1,-8), (-40,-34)
We will check each point by plugging it in the given equation and see if it satisfies the equation or not.
(0,5)
which is not true. Hence, not a solution.
(4,-2)
which is true. Hence, it is a solution.
(8,2)
which is not true. Hence, not a solution.
(-16,-17)
which is true. Hence, it is a solution.
(-1,-8)
which is not true. Hence, not a solution.
(-40,-34)
which is not true. Hence, not a solution.
