Question

What is the equation of the line that passes through the point (-6,-3) and has a slope of -1/6?

Answer 1

y = (-1/6)x - 4

Explanation:

Line equations are usually expressed in the following format:

y = mx + c

Where m is the gradient (slope), and c is the y-intercept.

We can fill in the value of m right away as we are given it in the question:

y = (-1/6)x + c

And we are given the point (-6,-3), so we can fill in the values for x and y, in order to find the value of c:

-3 = (-1/6)(-6) + c

Rearrange and simplify this:

-3 = 1 + c

c = -4

Finally, substitute the value of c back into the original equation to get the final equation of the line:

y = (-1/6)x - 4
