A knight on a chessboard is moved forward 3.6 cm from the centre of one square to another, then diagonally across at 45° to the centre of the destination square. How far

did the knight move in total? Give your answer to two decimal places.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
