Question

The line AB is shown on the grid.

Answer 1

a) The gradient of a line perpendicular to AB is -2.

b) equation of line is y=-2x+6

What is gradient?

The gradient is the measure of the steepness of a straight line.

a)The gradient of line is

=(-2-2)/(7+1)

=-4/8

=-1/2

So, gradient of a line perpendicular to AB is  -2

b)The coordinates of mid point (3, 0)

m = -2

So,

0= -6+ b

b= 6

So, equation of line is y=-2x+6
