Question

the graph of y equals negative x - 2 shown below use the graph to determine which of the ordered pairs is the solution to the equation

Answer 1

y = -x - 2

To check if an ordered pair is a solution to the equation, we have to replace the value of one variable and compute the other variable, as follows:

x = 1

y = -1 - 2

y = -3

Then, (1, -3) is a solution to the equation

x = -2

y = -(-2) - 2

y = 2 - 2

y = 0

Then, (-2, 0) is a solution to the equation

x = 4

y = -4 - 2

y = -6

Then, (4, -1) is not a solution to the equation

x = 0

y = -0 - 2

y = -2

Then, (0, 2) is not a solution to the equation, and (0, -2) is a solution to the equation
