Iforgot how to do this can you explain to me ?

A. y =⁵/₃x + 375

Step-by-step explanation:

Each square on the graph represents 25 tables or $125 in earnings.  

The graph appears to pass through the points (0, 375) and (300, 875).

Slope = m = Δy/Δx

          = (y₂ - ₁)/(x₂ - x₁)

          = (875 - 375)/(300 - 0)

         = 500/300

         = ⁵/₃.

The y-intercept (b) is at y = 375.

The equation for a straight line is

y = mx + b

Thus, the equation for your line is

y =⁵/₃x + 375

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
