Answer 2

i think it is b and c i just need checking!

Answer 3

you can work out the equation from the slope of the line and the coordinates of one of the points

use the general form

y - y1 = m(x - x1) where m = slope and (x1,y1) is a point on the line

Answer 4

ok so it is c and b just checking thx @welshfella here is medal

Answer 5

B and C

Answer 6

slope = 8/5

y - 5 = (8/5)(x - 1)
multiply through by 5
5y - 25 = 8x - 8
-8x + 5y = 17

Answer 7

oh so b and d?

Answer 8

arg so close! i hate being half wrong

Answer 9

b is correct

in another form its
