He will have to pay $3.25.
Let the number of miles traveled by a driver be x
The toll paid by the driver is then represented as $y.
Since there is a linear relation between the two, we can assume the equation can be written as:
y = mx + c
From the given data, we get
0.24 = m(0) + c
c = 0.25
Using the second point:
1 = m(1) + 0.25
m = 1 − 0.25 = 0.75
Hence, the equation is y = 0.75x + 0.25.
If x = 4, then:
y = 0.75 × 4 + 0.25
y = $5.50
Hence, He will have to pay $3.25.

Answer:
-9 = 0.45m
Step-by-step explanation:
0.45m -9 = 0.9m
-0.45m -0.45m
-9 = 0.45m
Step-by-step explanation:
We have been given the linear regression equation for a data set is y=-2.8x+70.8 where y is the temperature in degrees Fahrenheit and x is the number of hours since 8 am.
We can see that our given line is in slope-intercept form:
, where, m = Slope of line and b = y-intercept.
Upon comparing our given equation with slope intercept form we can see that the slope of the equation (m) is -2.8. The slope represents that temperature is dropping at a rate of 2.8 Fahrenheit per hour after 8 am.
