PLEASE HELP ASAP

lana [24]

First find midpoint: $\left( \frac{-1+5}{2}, \frac{6+5}{2}\right) = (2, 5.5)$

Find slope of line that passes through R and S: slope = $\frac{6-5}{-1-5} = \frac{-1}{6}$

Negative reciprocal of slope to get slope of perpendicular: new slope = 6

Line will be: $y-5.5=6(x-2)$

$y = 6x - 6.5$

I can tell me you’re asked to solve negative 4X -25 equals 8X +15 identify where one of them made an error

hammer [34]

x = - $\frac{10}{3}$

- 4x - 25 = 8x + 15

subtract 8x from both sides

- 4x - 8x - 25 = 15

- 12x - 25 = 15

add 25 to both sides

- 12x = 15 + 25 = 40

divide both sides by - 12

x = $\frac{40}{- 12}$ = - $\frac{10}{3}$
