Question 1029260: 1. Write the equation in slope intercept form: of the line that passes through (-1, 2) that is perpendicular to y=x-6.
2. Write the equation in slope intercept form: of the line that passes through (4,5) that is perpendicular to -2x-8y=18.
3. Write the equation in slope intercept form: of the line that passes through (4, 10) that is parallel to y=3x+8.
plzz help this is for my algebra 1 hw. I got y=2x-2 for 3. but I'm not sure if its correct thanks if u help.

You can put this solution on YOUR website!
Perpendicular lines have slope that are negative recpirocals.
Paralllel lines have slopes that are identical.
y=x-6
m%5Bp%5D%2A%281%29=-1
m%5Bp%5D=-1
So then using the point slope form,
y-2=-1%28x-%28-1%29%29
y-2=-%28x%2B1%29
y-2=-x-1
highlight%28y=-x%2B1%29

2. DO it the same way as #1.

3. m%5Bp%5D=3
y-10=3%28x-4%29
y-10=3x-12
highlight%28y=3x-2%29
