Put the equation into the form y = mx + b:
Where m = the slope and b = the y intercept.

Write the equation as $8y = -5x$ This puts $y$ on the left side of the equation.

Then solve for $y$ by dividing both sides by 8.

$8/8 xx y = -5/8 xx x" " 8/8 = 1$

y = $-5/8 xx x$

$m = -5/8$ so the slope is $- 5/8$

(Think m = mountain slope , the angle of the line)

$b = 0$ so the $y$ - intercept is at $(0,0)$

(Think b = the beginning, the place where the line starts.)
