We are given m (slope) = -1/3 and the point (-6, 5) on the line.
Let's use y = mx + b which is called the slope-intercept form for the equation of a line where b is the y-intercept (the point at which the line intersects the y-axis.
So in y = mx + b replace x with -6, y with 5 and m with -1/3.
We get 5 = -1/3(-6) + b Now solve for b by first simplifying -1/3(-6) and we get,
5 = 2 + b Now subtract 2 from both sides
-2 -2
3 = b
Finally, in the y = mx + b, replace m with -1/3, b with 3, and the equation of the line we are looking for becomes y = -1/3x + 3
