In this case: x 1 = - 10, y 1 = - 2;
x 2 = - 4 , y 2 = - 2
The distance between the points :

Answer:
d = 6
12 days. 60 is a quarter of 240. So, multiply 60 by 4 to get 240.
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
Answer:
ab - ac + db - dc
Step-by-step explanation:
you distribute the variables inside the parenthesis
Slope = (Y2 - Y1) / (X2 - X1)
Slope = (5 - 3) / (5 - 8) = 2/-3 = -2/3
Answer: (B) -2/3
