Y=mx+b is the equation used to solve. y>x+3 So start on b which in this case is 3, meaning plot the first point on 3. Then you move with x by using rise over run. also shown as rise/run. This means you would rise on the Y-axis using the value before x (also known as m) because there isn't one in this inequality that means we would go up one. Then you run to the right 1 because below the x is a 1. Because this is a greater then sigh you would shade above the line with a dotted line because it isn't equal to. Now try to do the next one on your own and tell me how you do.
Since the lines are perpendicular the opposite angle of labeled is also 60° and so would the two angles on the the lower just opposite way therefore 8x-4=60 -4 -4 8x=56 /8 /8 X=7
