Take any two points to find the slope of a line. The slope will be equal to:
(y2-y1)/(x2-x1) and any two points will do...
I'll use (-2,4) and (0,0) :P so the slope is:
(0-4)/(0--2)=-4/2=-2, now we know the slope is -2 so:
y=-2x+b (now we know b=0, but I'll use another point anyway to solve for b)
Let's use (-2,4) again...
4=-2(-2)+b
4=4+b
b=0
So the line is:
y=-2x
hope this helped!
Answer:
they scored 10 in the first quarter
Step-by-step explanation:
44-14=30

Answer:
Answer C
Step-by-step explanation:
If the polygon has n sides, then the number of diagonals the polygon has is
(n - 3)*n/2
So for a seven sided figure the number of diagonals would be
(7 - 3)(7)/2 = 4*7/2 = 28/2 = 14
