The answer is C. 7 x ( 2 x 2 )
70º
It's a supplementary angle so 180º - 110º
The statement on the bottom left is correct. (6 students studied for 20 to 24 hours)
First, plug in the given point into y=mx +b to find b (the y-intercept of the line). Use the same slope (m) in the equation since parallel lines have the same slope (3 in this case).
-1 = 3(4) +b
-1 = 12 + b Subtract 12 to both sides.
-13 = b
Now, put your m and b into y=mx+b.
The final answer/equation of your line is:
y=3x -13
