9. Find the slope of a line parallel to 3x - y = 1.

slope = 3

Step-by-step explanation:

The slope of a line parallel to the given equation share the same slope. Note the slope intercept formula:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

First, isolate the variable, y. Subtract 3x from both sides:

3x (-3x) - y = 1 (-3x)

-y = -3x + 1

Next, divide -1 from both sides:

(-y)/-1 = (-3x + 1)/-1

y = 3x - 1

You are solving for the slope of a line parallel to the given equation. Since you are solving for parallel, the slope would be shared.

3 would be the slope of the line.
