2 QUESTIONS 50 POINTS!!! Question 1: A car's odometer starts at 25 miles and for every 25 miles traveled, 1 gallon of gas is use
d. Based on this information, which graph best shows this relationship between the miles traveled, y, and the gallons of gasoline used, x? Question 2: When a window is open, the temperature in a room falls 5ºF every 15 minutes. Before the window is opened, the temperature was 70ºF . Use the Ray tool to make a graph that shows the temperature of the room, T, after the window has been open for m minutes.

Answer:
Step-by-step explanation:
y=-1/3x+9
This is written in the format y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
Perpendicular lines have a slope that is the negative inverse of the slope of the reference line, in this case -(1/3). The new slope is 3. equation is:
y = 3x + b
To find b, enter the given point, (-6,-2) and solve for b:
y = 3x + b
-2 = 3(-6) + b
-2 = -18 + b
b = 16
The full equation is y=3x + 18
