Answer:

if y = 5 than 2x - 5 = 5 we can simplify this too 2x = 10 ( by adding the 5 to both sides ) now we can simplify and get x = 5 ( by dividing by 2 ) so we get (5,5) as our first point. well since its in slope intercept form ( y = mx + b ) we can graph it.

Find the Mid point of (-5,-9) (-7,-4)

lyudmila [28]

Answer: ( -6 , -6.5 )

Step-by-step explanation:

The formula for calculating Mid - point is given by

M = ( $\frac{x_{1}+x_{2}}{2}$ , $\frac{y_{1}+y_{2}}{2}$ )

$x_{1}$ = -5

$x_{2}$ = -7

$y_{1}$ = -9

$y_{2}$ = -4

substituting into the formula , we have

M = $\frac{-5-7}{2}$ , $\frac{-9-4}{2}$

M = $\frac{-12}{2}$ , $\frac{-13}{2}$

Therefore : mid point = ( -6 , -6.5 )
