How do you find the slope and y-intercept for the line $11 x + 8 y = 40$ $11x + 8y = 40$ ?

$m = - \frac{11}{8}$ $m=-11/8$
$y = 5$ $y=5$

Explanation:

Given -

$11 x + 8 y = 40$ $11x+8y=40$

If the equation of a straight line is in the form

$a x + b y = c$ $ax+by=c$

Then, its slope is given by

$m = - \frac{a}{b} = - \frac{11}{8}$ $m=-a/b=-11/8$

y-intercept is

$y = \frac{c}{b} = \frac{40}{8} = 5$ $y=c/b=40/8=5$
