## What is the slope of a line parallel to the y-axis?

undefined

The slope of the equation of line parallel to y axis is undefined. The line parallel to y axis is at an angle of 90º to the x – axis and the slope of this line is tan90º, which is undefined.

## What is the slope of a perpendicular line to?

negative reciprocals

The slopes of two perpendicular lines are negative reciprocals of each other. This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m.

**What is the slope of the y-axis?**

The y‐axis or any line parallel to the y‐axis has no defined slope.

**What is the slope of a line perpendicular to the y-axis select undefined if applicable?**

The y-axis is a vertical line. A vertical line has a slope of 10 which is undef or undefined. The negative reciprocal would be 01 or 0 . So, the slope of the perpendicular would be 0 .

### What is the slope of a line perpendicular to Y =- 2?

As we know, the slope of the line Y= -2 is zero. So the slope of a line perpendicular to Y= -2 is 90 degree.

### Why is slope of y-axis not defined?

The slope of a vertical line is undefined, and can not be found. This is because the denominator of the rise over run fraction is always 0.

**What is the slope of a line defined by Y − 7?**

Slope is zero; Y-intercept at x=0,y=−7.

**Does perpendicular lines have the same slope?**

Perpendicular lines do not have the same slope. The slopes of perpendicular lines are different from one another in a specific way. The slope of one line is the negative reciprocal of the slope of the other line. As with parallel lines, we can determine whether two lines are perpendicular by comparing their slopes.

#### Do perpendicular lines have the same exact slope?

Perpendicular lines. Perpendicular lines do not have the same slope. The slopes of perpendicular lines are different from one another in a specific way. The slope of one line is the negative reciprocal of the slope of the other line.

#### Do perpendicular lines have opposite slopes true or false?

If two lines are perpendicular and neither one is vertical, then one of the lines has a positive slope, and the other has a negative slope. Theorem 105: If two nonvertical lines are perpendicular, then their slopes are opposite reciprocals of one another, or the product of their slopes is −1.

**Is the slope of a line is the same as the parallell line?**

Parallel lines and their slopes are easy. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope – and lines with the same slope are parallel.

**What is the slope of a line that is parrel to the Y- axis?**

Properties of Vertical Lines The equation of a vertical line in the graph, which is parallel to y-axis is x = a. The slope of a vertical line is infinity or undefined as it has no y-intercept and the denominator in the slope formula is zero. To check whether the relation is a function in maths, we use a vertical line.
