For two dimensional lines: Get the formulas for the two lines into a format so that you can evaluate the slope. If the slopes are different, then they will intersect. If the slopes are the same, then you have two parallel lines, or possibly, the two equations describe the same line.
No, because although perpendicular and intersecting lines do touch, parallel lines never meet.
the definition of intersecting lines is: two lines that meet and cross at the same at the same place
No.
Two lines with the same slope are parallel.
A graph of two simultaneous linear inequalities in two variables that have no intersecting regions must contain two lines with the same slope.
No. In order to be parallel, two lines would have to have the same slope, and different intercepts.Why? Two lines with different slopes, but the same intercepts would result in two intersecting lines. Two lines with the same slope, and the same intercept would result in the same line. Two lines with the same slope, and different intercepts would be parallel.

True
No but if the two lines are parallel then they will have the same slope.
No, because although perpendicular and intersecting lines do touch, parallel lines never meet.

No.
Two linear equations (or lines) with the same y-intercept and different slopes are intersecting lines. They intersect at the y-intercept. If the slopes are negative reciprocals (ex: one slope is 3 and one slope it -1/3) then they are perpendicular lines.
Two lines with the same slope are parallel.
The slope between two parallel lines is identical. This is because parallel lines have the same slope and will never intersect. The slope of a line is a measure of its steepness, and when two lines are parallel, they will have the same steepness, resulting in the same slope. Therefore, the slope between two parallel lines will always be equal.
Two or more lines containing the same point are intersecting.
