# How do you find the slope & y-intercept of the equation 3x + 5y = 15?

Mar 24, 2018

Slope is $- \frac{3}{5}$ and y-intercept is $3$

#### Explanation:

$3 x + 5 y = 15$ [Make y as subject]

$\therefore 5 y = - 3 x + 15 \mathmr{and} y = - \frac{3}{5} x + 3$

Comparing with slope intercept form of straight line $y = m x + c$

we find here slope $m = - \frac{3}{5}$ and y-intercept as $c = 3$

Therefore , slope is $- \frac{3}{5}$ and y-intercept is $3$
