What does it mean if two lines have same slope?
parallelIf lines are parallel, they slant in exactly the same direction. If they are nonvertical, their steepness is exactly the same. Theorem 103: If two nonvertical lines are parallel, then they have the same slope.
Can two lines have the same slope and not be parallel?
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
How do you know if two lines have the same slope?

Are all lines with the same slope the same line?
Because all lines with the same slope will slant at the same angle, parallel lines have the same slope. Perpendicular lines (lines that intersect at a 90 degree angle) have slopes that are negative reciprocals.
Do parallel lines have the same slope and same Y intercept?
Parallel lines have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.
What happens if two linear equations have the same slope?
When lines have the same slope and different y-intercepts they are parallel lines. Parallel lines never intercept.
How many lines have the same slope?
Two lines are parallel if the slopes are equal (or, if both lines are vertical).
Do all lines have a slope?
The number "zero" exists, so horizontal lines do indeed have a slope. But vertical lines don't have any slope; "slope" simply doesn't have any meaning for vertical lines.
How do you compare the slope of two lines?

So this negative 3 is a steeper slope than this one which is a slopeMoreThan a slope of negative 1/2. So this negative 3 is a steeper slope than this one which is a slope of negative 1/2. And similarly on the right side the slope of positive.
How do you check if the slope is correct?
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
How do you find the slope of two lines?
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
