square flower bed is 3m 80cm long •lt is extended by digging a strip 50cm wide all around it• find the area of the enlarged flower bed and also the increase in the area of the flower bed good ans ​

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

(-1,-0.5)
