Data:
Truck 2 started $2 and sold 2 tacos for $1
A is the amount of money and T is the number of tacos sold
The equation of a line has the next general form:
[tex]y=mx+b[/tex]m is the slope or rate of change and b is the y-intercept (value of y when x is 0)
For the given situation:
1. To find the slope use the data as follow:
Truck 2 started $2:
[tex]\begin{gathered} m=\frac{A}{T} \\ \\ \\ m=\frac{1}{2} \end{gathered}[/tex]2. The y-intercept is the money truck 2 started (initial value)
[tex]b=2[/tex]Then, the equation for line that describes amount of money for taco truck 2 is:
[tex]A=\frac{1}{2}T+2[/tex]
