Find the slope of the line going through the points (11,5) and (20,5)
1 answer:
So remember the formula for working out the slope: (y2 - y1) ÷ (x2 - x1) We already know two points: (11, 5) and (20, 5) (Remember points are like (x, y) Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11 Substitute these into the formula from the start: (y2 - y1) ÷ (x2 - x1) (5 - 5) ÷ (20 - 11) 0 ÷ 9 And we can determine the slope is equal to 0 as 0 ÷ 9 = 0
