Jylian said:This is the problem I need help with.
Give the slope of a line perpendicular to the given line.
y= 1/2x-3
If two lines are perpendicular (and neither of the lines is horizontal or vertical), then the slopes of the lines are OPPOSITE RECIPROCALS. That is, the slopes of the two perpendicular lines will have product of -1.
If two lines, neither of which are horizontal or vertical, are perpendicular, then when you multiply their slopes, you will get -1.
Ok....
You have a line whose equation is'
y = (1/2)x - 3
What is the slope of this line (remember, the slope-intercept form for the equation of a line with slope m and y-intercept b is y = mx + b)
The slope of any line perpendicular to a line with slope "m" is "-1/m"
Show us what you have done with this information.
