Question

Find the equation of a straight line  with slope − 1/3 and y-intercept − 4.

Answer in Brief

Solution

Here, \[m = - \frac{1}{3}, c = - 4\]

Substituting the values of m and c in y = mx + c, we get,

\[y = - \frac{x}{3} - 4\]

\[ \Rightarrow x + 3y + 12 = 0\]

Hence, the equation of the straight line with slope

\[- \frac{1}{3}\] and y-intercept 4 is x + 3y + 12 = 0
