HOW CAN YOU DETERMINE IF TWO LINES ARE PERPENDICULAR?
Go look back on your post, I've answered this already.
To determine if two lines are perpendicular, you can use the slope-intercept form of the lines. The slope-intercept form of a line is given by the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
If two lines are perpendicular, their slopes multiply to give -1. This means that if the slope of one line is m1 and the slope of the other line is m2, then m1 * m2 = -1.
To determine if two lines are perpendicular, follow these steps:
Step 1: Write the equations of the lines in slope-intercept form (y = mx + b).
Step 2: Compare the slopes of the lines. If the product of the slopes is -1, then they are perpendicular. If not, they are not perpendicular.
Note: If one of the lines is vertical (having an undefined slope), and the other line is horizontal (having a slope of 0), then they are also perpendicular.
By following these steps, you can easily determine if two lines are perpendicular.
