Answer :
Answer
(6, -21) is a solution to the equation y = -5x - (-9)
Step-by-step explanation:
Given the equation
y = -5x - (-9)
We want to know if (6, -21) is a solution the above equation
let x = 6 and y = -21
substitute the value of x and y into the above equation
-21 = -5(6) - (-9)
-21 = -30 + 9
-21 = -21
Hence, (6, -21) is a solution to the equation y = -5x - (-9)
