Question

13.Calculate the slope of AD .
14. Write the equation for AD
15. Calculate the slope of BD
16. Calculate the slope between the points (-6, 9) and (4, 11).

17. Calculate the slope between the points (3, 7) and (-3, 7).

plz i need help i suck with the whole slope thing!
picture below

Answer 1

slope = y2-y1 / x2-x1

Answer 2

fr AD
slope is (-1-3)/2-1 = -4/1 = -4

Answer 3

equation of AD
is y-(-1)=-4(x-2)
y+1=-4x+8
y=-4x+7

Answer 4

oooo ok thank u very much but can u help with the other 2

Answer 5

slope of BD is
(-1-2)/2-5) = -3/-3 = 1

Answer 6

finding the gradient (11-9)/4+6
=1/5

Answer 7

i ve used the gradient frmula which is m=(y2-y1)/(x2-x1)

Answer 8

0 isnt a answer

Answer 9

slope is undefined

Answer 10

thank u

Answer 11
