Step-by-step explanation:
Hello : let A(-7,3) B(-6,-1)
the slope is : (YB - YA)/(XB -XA)
(-1-3)/(-6+7) = -4/1 =-4
an equation is : y=ax+b a is a slope
y = -4x +b
the line through point B (-6,-1) : -1 = (-4)(-6)+b
b = -25
the equation is : y =-4x-25
Answer:
16 red marbles
Step-by-step explanation:
8 red
9 yellow
7 green
total = 8 + 9 + 7
p(red) = 8/24 = 1/3
Add r number of red marbles to the total.
8 + r red
9 yellow
7 green
total = 8 + r + 9 + 7 = r + 24
p(red) = (8 + r)/(r + 24) = 3/5
Cross multiply.
40 + 5r = 72 + 3r
2r = 32
r = 16
Answer: 16 red marbles
It would be about 7.9 rounded to nearest hundredth
