I have 2 questions :) Appreciate any help
Tell whether the lines for each pair of equations are parallel perpendicular or neither.
y=1/4x+10
-2x+8y=6
a parallel
b. perpendicular
c. neither

Write the equation of a line that is perpendicular to the given line that passes through the given point.
y-3=8/3(x+2);(-2,3)
a. y+3=-3/8(x-2)
b. y-3=-3/8(x+2)
c. y-2=-3/8(x+3)
d. y+3=3/8(x-2)

Do you know how to determine if two lines are parallel or perpendicular? 
lines are parallel if they have the same slope (m)
lines are perpendicular if their slopes are negative reciprocals (p and -1/p) 
lines are neither par. nor perp. if their slopes don't follow these relationships.

Does this make sense/do you understand/know this?

Yeah I guess, but I don't understand how to solve this... I'm basically completely lost. With both

So how can you calculate the slopes of the 2 equations in the first question? The first equation is in slope-intercept, y = mx + b, so m1 = 1/4. If you rewrite the 2nd equation to be in slope-intercept form you can tell what m2 is. Let me know what you've got, and I'll continue.
