Find the slope of a line parallel to 3x – y = 1.
2 answers:
Answer:
3
B is correct option.
Step-by-step explanation:
The equation of the line is
Convert this equation in slope intercept form y = mx + b, where m is the slope and b is the y-intercept.
Subtract 3x to both sides of the given equation
Divide both sides by -1
On comparing this equation with slope intercept form of a line y= mx+b
m = 3, b = -1
Hence, slope of the given line is 3.
Now, we know that parallel line have same slope.
Thus, slope of the required line is equal to the slope of given line.
Therefore, the slope of the required line is 3.

let's notice that the angle -150° has a reference angle of 30°, so any trigonometric function for either angle will be the same value, however, let's recall that the sine or y-coordinate is negative on the III Quadrant, so sin(-150°) is the same as sin(30°) BUT negative, -sin(30°).
