How can you tell which lines are perpendicular?
That the slopes of the lines are the opposite of each other and negative. Ex: y=2/3x+b then the line perpendicular to it is y=-3/2+b
Do perpendicular lines have the same equation?
The general form of an equation for a line isaX + bY = c.Since perpendicular lines have different slopes and different x and y intercepts the parameters a, b, and c are different for perpendicular lines
What makes 2 equations perpendicular?
Technically, equations are never perpendicular to one another. However, the equations of lines can result in their lines being perpendicular. Using y=mx+b, to have a perpendicular line, you have the negative reciprocal of m.
How many lines of symmetry does the letter B have?
The letter B has one set of line symmetry.The top of the B and the bottum.
How is it determined whether the lines passing through some specified points are parallel perpendicular or neither?
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
