Question

determine the slope of the line 8x-4y-9=0

Answer 1

Let the line equation represented as

${\bold {\large {y=mx +c }}}$

on comparing it with the given equation

8x-4y-9=0

8x-9=4y

$2x - \frac{9}{2} = y$

$2x + ( - \frac{ 9}{2} ) = y$

so slope will be

${\bold {\pink {\mathcal {\boxed{2}}}}}$

Answer 2

Answer:

Hey dude....

$8x - 4y - 9 = 0 \\ - 8x \: \: \: \: \: - 8x \\ - 4y - 9 = - 8x \\ - 9 \: \: \: - 9 \\ - 4y = - 8x + 9 \\ devided \: by \: 4 \: on \: both \: side \: to \: have \: y \: by \: itself \: and \: you \: get \: \\ y = 2x - \frac{9}{4} \\ the \: slope \: in \: this \: equation \: is \: 2x \: so \: ans \: is \: 2.$

Hope it helps you!!!
