Answer: [D]: " y = -3x + 29 " .
______________________________________________
Step-by-step explanation:
______________________________________________
Given the solution, "(10, -1)",
_______________________________
Answer choice, "D", "y = -3x + 29" ; is the only answer choice given that has: "(10, -1)" as a solution; (that is, when "x = 10; y = -1").
__________________________________________________________
Given the equation in the answer choice given in "Answer choice: [D]:
__________________________________________________________
→ " y = -3x + 29" ;
__________________________________________________________
Let us substitute the "x-coordinate", which is: "10", for "x";
and see if "y = -1" ;
____________________________________________________
→ -3*(10) + 29 =? -1 ?? ;
____________________________________________________
→ -30 + 29 =? -1 ?? Yes!
____________________________________________________
So, the answer is: Answer choice: [D]: " y = -3x + 29 " .
