Suppose y varies directly with x. Write a direct variation equation that relates x and y. Then graph the equation.
y=5.4 when x=0.9
the equation of variation is y =
y = kx
To find the value of k, we can use the given information:
5.4 = k * 0.9
Dividing both sides by 0.9:
k = 6
Thus, the equation of variation is:
y = 6x
To graph this equation, we can plot the points (0.9, 5.4) and (1.8, 10.8), and draw a straight line through them. The graph will be a straight line passing through the origin.
