Final answer:
The corresponding equation for the graph of a proportional relationship with the point (8, 4) is y = (1/2)x.
Step-by-step explanation:
The given point (8, 4) represents a proportional relationship. In a proportional relationship, the ratio between the two quantities remains constant. To find the corresponding equation, we can use the formula y = kx, where y represents the dependent variable, x represents the independent variable, and k represents the constant of proportionality.
To find the value of k, we can substitute the given coordinates (8, 4) into the equation and solve for k:
4 = k * 8
Dividing both sides by 8, we get:
k = 4/8 = 1/2
Therefore, the corresponding equation for the given graph is y = (1/2)x.
