1. To find the slope do the rise/sun. So you need to create a right triangle by connecting the points. If the line goes from left to right than it is a negative slope. But if it goes from right to left than it is a positive slope. Count how many down from the top point to the bottom and then count how many to connect the 2. But the points you give make a straight line. Meaning the slope is 0. Hope someone answer the rest of your questions because this is the only one I know!
(8,7)(11,7)....when u have y values that r the same, it is a horizontal line. A horizontal line has a slope of 0. ================ not 100% sure....but I think it may be B =============== point F is (-2,3) =============== P = a + b + c a = (-8,-4), b = (-7,-8), c = (-6,-2) distance from a to b = 4.12 distance from a to c = 2.83 distance from b to c = 6.08 P = 4.12 + 2.83 + 6.08 = 13.03 <== ====================== d = sqrt W^2 + L^2 d = sqrt 9^2 + 5^2 d = sqrt (81 + 25) d = sqrt 106 d = 10.30 <== ====================== 3x + 1 = 1/3x + 9...multiply by 3 9x + 3 = x + 27 9x - x = 27 - 3 8x = 24 x = 24/8 x = 3
AK = 3x + 1 AK = 3(3) + 1 AK = 9 + 1 AK = 10 =============== Line B has a slope of 2
