Which of the following numbers is between -3/4 and 5/8
-1
-1/2
7/8
0.9

is the required number.

Step-by-step explanation:

In order to find the number we first convert them into decimal expansions

Thus, we need a number that lies between -0.75 and 0.625.

The decimal expansion of given numbers are:

-1

0.9

Clearly, when we see all the the four numbers, -0.5 lies between -0.75 and 0.625.

That is the required number lying between and is

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
