Answer:
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
