You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.

If one slope is -1 what is the slope of the perpendicular slope?

The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.


What is a line wxtending from the upper lift to the lower right has this type of slope?

The line has a negative slope (or negative gradient).When the angle between the line and the positive direction of Ox is obtuse then the slope is negative. Conversely, when the angle is acute, the slope is positive.


What can you say about a slope a regression line for variables that are negatively associated?

The slope will be negative.The slope will be negative.The slope will be negative.The slope will be negative.


Does a steep line always have a negative slope?

A line doesn't have a negative slope if it's steep or not. Possitive and negative slope is determined by the way it goes up or down. When you look at a line from the left to the right, if it gets higher as you get closer to the right, then it has a positive slope. On the other hand, if you also look at it from left to right and the line goes down as it nears the right side, it has a negative slope. If the line is horizontal, it has a slope of 0. If the line is vertical, it has no slope.


What is the slope of the line if it's inclined to the left?

What is the formula for Perpendicular Slope?

Line a with a slope perpendicular to that of line b has a slope that is the negative reciprocal of line b's. So basically the negative reciprocal.


What does it mean for a line to have a negative slope?

If a line has a negative slope it is going 'down hill' and if it has a positive slope it is going 'up hill'


Is the inverse of a line with positive slope a line with negative slope?

Never.


What is the slope of a line that decreases from left to right?

We know that its slope is negative, but without an equation or some points the line passes through we can't determine the actual value of the slope.


How do you know if a slope is positive or negative?

There shouldnt be a slope on your test.... There should be 2 straight lines which means postive. One straight line means negative.


Is a slope of a line always positive?

No because the slope of a line can be positive or negative

What is negaitve slope?

You're familiar with the xy-plane. A line with negative slope is one that goes down toward the right. A curve has a negative slope at a point if the tangent line to the curve at that point has a negative slope.
