The amount of money earned for hours spent babysitting is displayed on the graph. Derive the equation of the line through the origin.
A.
y = $11x
B.
y = $5.50x
C.
y = $22x
D.
y = $16.50x
B. y = $5.50x
To find the equation of the line through the origin, we need to find the slope. We can see from the graph that for every hour spent babysitting, the amount earned is $5.50.
Therefore, the equation of the line through the origin is y = $5.50x.
