Find the gradient of lines A and B

The gradient of lines A is 8 and B is -4

Step-by-step explanation:

As we know, the  gradient of a line is its slope.

The formula to find the slope of a linear line is:

m =

As we can see the line A goes through points:

C (x1, y1) =  (0, -6)

D (x2, y2)=  (2.5, 14)

<=> the slope of line A is:

=

=

=

As we can see the line A goes through points:

E (x1, y1) =  (2, 0)

F (x2, y2)=  (0, 8)

<=> the slope of line B is:

=

= -4

Hence,  the gradient of lines A is 8 and B is -4

i do not know this sorry : (

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
