For points (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
(3,4) and (6,6), slope is (6-4)/(6-3)=2/3
(4,-4) and (2,-7), slope is (-7-(-4))/(2-4)=(-7+4)/(-2)=-3/-2=3/2
for ax+by=c
slope=-a/b
3x+4y=12
slope=-3/4
Answer:
1/4
Step-by-step explanation:
The number of kids who brought their lunches is 3/7 of 84.
3/7 of 84 = 3/7 * 84 = 3/7 * 84/1 = (3 * 84)/(7 * 1) = 252/7 = 36
36 kids brought their lunches.
9 of the 36 kids got a slice of pizza.
The fraction is 9/36 = 1/4
Answer: 1/4
<span>ill try to help get u started
y = x^2 +1 ;
</span>The y values are 10,5,2,1,2,5,10
For y = x^2-1, they are
<span>8,3,0,-1,0,3,8</span>
The answer is 61. hope that help.
