Answer:
b
Step-by-step explanation:
C. The number of times a dessert was offered at a special price.
Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)
60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges
255 litres for 340 km
for 1 km = 255/340 litres
for 100 km = 255/340 * 100 = 75 litres
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
(-8, 6)
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b
38 = b
So the equation is:
y = -4 + 38
