Which function describes this graph a. y=(x+5)(x-4) b. y=(x-3)(x-6) c. y=x^2-2x+4 d. y=x^2*9x+18

I believe that the answer is B

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

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
