Answer:
-3x+1y=-1
or
3x-1y=1
or
by multiplying with 1/3 the first equation we get
-1x+1/3y=-1/3
or from second equation
1x-1/3y=1/3
Step-by-step explanation:
y-y1=m(x-x1)
y1=-7
x1=-2
m=3
so
y-(-7)=3(x-(-2))
y+7=3(x+2)
y+7=3x+6
-3x+y=6-7
-3x+ 1y= -1
The two equations:
Daisy’s: y = 4x + 14
Donald’s: y= 2x + 26
The point of intersection is (6, 38)
This point refers to how many of passengers it will take for both equations to have have the same cost output.
Daisy’s deal is better if you have less than 6 passengers. We can tell because the line for the equation is lower than Donald’s line. Donald’d deal will be better if you have more than 6 passengers since the line is lower than daisy’s deal.
Step-by-step explanation:
location
of the distribution.
86. Is a negative slope because it slants down from left to right.
87. Is positive slope because it slants up from left to right.
88. Is an undefined slope because it is vertical.
89. Is has a slope of zero because it is horizontal.
