Y - y₁ = m(x - x₁)
y - 5 = -8(x - 2)
y - 5 = -8(x) + 8(2)
y - 5 = -8x + 16
<u> + 5 + 5</u>
y = -8x + 21

X − 6 = 63 − 10(x + 8)

il63 [147K]

$\red { \green {\boxed {\boxed{Answer}}}}$

$x - 6 =63 - 10(x + 8)$

$x - 6 = 63 - 10x - 80$

$x - 6 = 63 - 80 - 10x$

$x - 6 = - 17 - 10x$

$x - 6 + 10x = - 17$

$x + 10 x- 6 = - 17$

$11x - 6 = - 17$

$11x = - 17 + 6$

$11x = - 11$

$x = \frac{ - 11}{11}$

$x = - 1$
