Question

What is the equation of the line that contains the point (3,-1) and has the same slope as the the line y=1/3x+5

Answer 1

y = 1/3x - 2

Explanation:

Line y = 1/3x + 5 has slope 1/3, so the line we are looking for also has slope 1/3.

y = 1/3x + b

We know a point, so we plug in the values of x and y, and we solve for b.

y = 1/3x + b

-1 = (1/3)(3) + b

-1 = 1 + b

b = -2

Now that we know b, the equation is:

y = 1/3x - 2
