Answer:
y = (2 - 7) / (6 - (-9)) * (x - (-9)) + 7
y = -5 / (6 + 9) * (x + 9) + 7
y = -5 / 15 * (x + 9) + 7
y = -1/3 * (x + 9) + 7
y = -1/3 * x - 3 + 7
y = -1/3 * x + 4
Step-by-step explanation: In this equation, it's important to understand that the number 5 is the coefficient on the variable M. This just means that -5 "times" M equals -40. So, whenever you see a number next to a variable, it means multiplication.
If we were to solve, we would just divide both sides of the equation by 5. On the left the 5's cancel and on the right, -40 divided by 5 is -8.
Answer:
B
Step-by-step explanation:
9(5)+8=53
All you have to do is plug 5 in for x
Answer: x = 12, y = -8
Step-by-step explanation:
If you do substitution:
4(-y+4) + 6y = 0
-4y + 16 + 6y = 0
2y + 16 = 0
2y = -16
y = -8
x = -(-8) + 4
x = 8 + 4
x = 12
