10 1/2 I am pretty sure its right
The y intercept is 0, and the slope is 5x.
Equation: y = 5x +0.
Answer:
what?Can you write better?
The number has 2 digits - let's call them x and y. The positive difference between the two combinations (lowest-highest and highest-lowest) is always equal to the positive difference of x and y, multiplied by 9.
For example:
76 and 67: 76 - 67 = 9 and ((7-6)*9) = 1*9 = 9
73 and 37: 73 - 37 = 36 and ((7-3)*9) = 4*9 = 36
D. You can find a perpendicular line by finding the inverse equations (-(1/)2 x+3
