But this is not a question. proof? no question mark
Degree is the value of the highest power of the variable, and hence in this case is 8
The answer is 8and 10 when you divided is 0.8
Slope = (y2 - y1) / (x2 - x1)
(-9,6)....x1 = -9 and y1 = 6
(-3,9)...x2 = -3 and y2 = 9
now we sub and solve
slope = (9 - 6) / (-3 - (-9) = 3 / (-3 + 9) = 3/6 = 1/2 <=
My explanation is attached below.
