Notice how the x-2 on the numerator and denominator cancel out, as well as the x+1. You are left with 8(x+2)/4 which is 2(x+2) which results in your answer, B, or 2x+4.

Work out the co ordinates of the midpoint of (-2,-1) and (-2,4)

s2008m [1.1K]

Answer:

$(-2,\frac{3}{2})$

Step-by-step explanation:

To find the midpoint, simply use the Midpoint Formula.

The Midpoint Formula states that for two points $(x_1,y_1)$ and $(x_2,y_2)$ , the midpoint will be: $(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$ .

So, here, $(x_1,y_1)$ = (-2, -1) and $(x_2,y_2)$ = (-2, 4). The midpoint is then: $(\frac{-2+(-2)}{2} ,\frac{-1+4}{2} )=(\frac{-4}{2} ,\frac{3}{2} )=(-2,\frac{3}{2})$
