Answer:
Situation: You start out with $30 and spend $2.50 every day on a soda.
Step-by-step explanation:
The equation of a line is y = mx + b
b = y-intercept
m = slope, rise/run
The line crosses the y axis at 30, so b is 30
Now for the slope, rise/run.
Start at 30 on the y-axis and go down to 25, that is a rise of -5. Now you are at (0, 25) on x-axis. Move right to the point (2, 25). The run is 2.
m = -5/2
The equation of the line is y = -5/2x + 30
