Question

Reduce the following equations into slope - intercept form and find their slopes and the $y$ - intercepts.
(i) $x+7y=0$,
(ii) $6x+3y-5=0$,
(ii) $y=0$.

Answer 1

(i) $x+7y=0$

$y=\frac{-1}{7}x+0$

slope $\Rightarrow \frac{-1}{7}$

intercept $=0$

(ii) $6x+3y-5=0$

$y=-2x+5/3$

slope $=-2$

intercept $=5/3$

(iii) $y=0$

slope $=0$

intercept$=0$
