A is the point (2,-5) B is the point (4,-9) show that the gradient of the line passing through A and B is -2

According to the number line, what is the distance between points a and b? v ++ + + + + -16 -14 -12 -10 -8 + 6 + 4 + -2 + 0 + 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 o6 units o 7 units 12 units o 14 units

Solve: 3x+y=6 4x-2y=18 show all work !
