If two lines are perpendicular, then they will have slopes that are negative reciprocals to each other. An example of negative reciprocals are 2 and -1/2
6.Now with line 2, I have to convert it to slope intercept form. Firstly, subtract 2x on both sides of the equation:![-5y=-2x+8](/tpl/images/0080/5048/d1e60.png)
Next, divide both sides by -5 and your slope-intercept form is![y=\frac{2}{5}x+\frac{8}{5}](/tpl/images/0080/5048/56bc9.png)
Now since 2/5 is not the negative reciprocal of -2/5, these lines are not perpendicular.
7.It's pretty much the same process; convert to slope-intercept and determine if negative reciprocal. This time I'll brush through them:
Now since 2 is the negative reciprocal of -1/2, these lines are perpendicular.
