The slopes of the given lines are -3 and
. Since the product of slopes is -1, the lines are perpendicular.
Certainly! Let's explicitly show the calculations for the slopes of the given lines:
Equation 1: y = -3x + 6
This equation is already in the slope-intercept form (y = mx + c), where the slope (m) is the coefficient of x. In this case, the slope is -3.
Equation 2:

Similarly, this equation is in slope-intercept form, and the slope (m) is

Now, we compare the slopes:
For parallel lines, slopes must be identical.
For perpendicular lines, the product of slopes must be -1.
In this case, since
is the negative inverse of -3 (because
), the lines are perpendicular.
Que. unit 3: parallel & perpendicular lines homework 6: slope-intercept form & standard form determine if the equations are parallel, perpendicular, or neither y=-3x+6 and y=1/3 x-8
