k these are the questions, ive done half..

a line passes through the points A(1, -3) and B(3, 5). Find:

a) the slope of the line;

b) the quation of the line in the form y = mx + ba(x1, y1) b(x2, y2)

a(1,-3) b(3, 5)

m = (y2 - y1)/(x2 - x1)

m = (5 - 3)/(3-1)

m = 2/2

m = 1

is this right??

c) the slope of a line parallel to AB;y = mx + b

y = 1x + b

y = 1(3) + b

y = 3 + b

3 = b

y = 1x + 3

is this right?

**HELPPP!!! ASAP**

d) the lope of a line perpendicular to AB.

**HELPPP!!! ASAP**

i just need help on the last to and i need verification on the first thats all, thanks!!! btw this is gr 9 math... yes i failed last year lmfaoo >_<
