find the equation that represents the proportional relationship in this graph, for ( y ) in terms of ( x ).
find the equation that represents the proportional relationship in this graph, for ( y ) in terms of ( x ).
Answer
Explanation:
Step1: Recall the proportional relationship formula
The equation for a proportional relationship is ( y = kx ), where ( k ) is the constant of proportionality.
Step2: Find the value of ( k )
From the graph, when ( x = 1 ), ( y = 2 ). Substitute into ( y = kx ): ( 2=k\times1 ), so ( k = 2 ).
Answer:
( y = 2x )
