Answer:
yes, (0, -7) is a solution
Step-by-step explanation:
To check if a coordinate is a solution to an equation, we substitute the value of the x into the equation to check if the value of the y is consistent with the coordinate.
Coordinate = (0, -7)
Equation: y = x² - 2x - 7
Sub (x = 0) into y = x² - 2x - 7
y = (0)² - 2(0) - 7
y = -7
When x = 0, y = -7
Therefore (0, -7) is a solution.
