Answer:
y = -3x + 6
Step-by-step explanation:
Slope-intercept form:
y = mx + b
m (slope) =
or -3
b (y-intercept, or where the line crosses the y-axis) = 6
y = -3x + 6
The formula of a slope:

We have the points (2, 5) and (4, 10). Substitute:

This means that 2.5mm of rain falls every hour
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.
Answer: 63.75 = 85h
Solving gives 0.75 hours.
Step-by-step explanation:
we now that speed = distance / time
therefore time will be Distance / speed
Given that distance = 63.75miles
Speed= 6=85miles per hour
Time(h) = 63.75miles/ 85.---- equation 1
But from the options given, the equation that can also be used to find number of hours is
63.75 = 85h
such that making h subject of formula still give us
h= 63.75/85 as in equation 1 above
solving gives that Time ( h) = 0.75 hours .
