Math representation of real-world using straight-line equation
y=mx+by = mx + by=mx+b
Gradient (rate of change)
yyy-intercept (starting value when x=0x = 0x=0)
m=y2−y1x2−x1m = \frac{y_2 - y_1}{x_2 - x_1}m=x2−x1y2−y1 or Rise over Run
Independent variable (value we know or choose)
Dependent variable (value we calculate)
Rate of change, cost per item, speed, or rate of flow
Base fee, initial amount, or starting value
Calculate gradient using two points, identify intercept
