the standard equation for a line is y=mx+b
where y is the dependent value, x is independent, m is the slop and b is the y intercept
your slope is 3 divided into 5, which means 3 is going into 5, we can simply write this as 5/3
the y intercept is already given so you just have to plug these values into the equation
y=5/3x+5
