Question

What is the equation of the line that is

parallel to the line y = 1x – 3 and passes
through the point (0, – 3)

Answer 1

y = 1x - 3

Explanation:

Note that the given line has slope +1.

Any line parallel to this line must also have slope +1.

Apply the slope-intercept form y = mx + b:

Inserting -3 for y, 0 for x and 1 for m, we get the y-intercept

-3 = 1(0) + b, which tells us that b = -3 and that the desired equation is

y = 1x - 3
