find the equation of the line with the given properties. write the equation in slope intercept form if possible
1. contains (5,6) and (4,8)
2. contains (5,4) and is parallel to
x=5
3. contains (7,8) and is perpendicular to y=6
please show how you got the answers for each one i have more to do on each but don't know how to do it

1.
y6 = (86)/(4+5) (x+5)
y = 2/9 x + 64/9
2.
x=5 is a vertical line. So,
x = 5
3.
y = 6 is a horizontal line. Perpendiculars are vertical lines. So,
x = 7
