Can you start by writing an equation from the info
Ok so first you would write out the problem and on the side multiply six times 10 until you can't get 60 out of your number any more then you find out how many times 6 goes into the remainder and up the amount of times 6 went into 258 and whet ever is left over is your remainder
Since 2x+y>4 you get y>4-2x. Then you draw the line y=4-2x then you are interested in everything above the line not including it since it is y>4-2x so it is a dashed line. You need to shade the side that satifies the inequality and since it is every pair (x,y) where y>4-2x, you need to shade everything above the line which is the side that does not include the origin. So the answer is C.
Perpendicular,
Explanation:
I just drew it down on paper
