i really don't understand these. please help. thank you so much.

a.five sixths

b.-five sixths

c.six fifths

d.-six fifths
2.Choose the equation of the line passing through the point (6, -2) and parallel to y = x + 7
a.y = x + 8

b.y = x - 4

c.y = x + 4

d.y = x - 8
3.Which of the following is an example of no correlation?

a.Age vs commute time to school

b.Time worked vs money earned

c.Number of movie tickets purchased vs total bill

d.Time eating vs food left

2) two lines are parallel when they have the same slope
|dw:1343839444339:dw| and when ur given the slope and a point the equation of the line would be |dw:1343839494871:dw|
