To know the value of the slope, first lets look at the equation of line as follows:
Equation of the line is
y=mx + b
According to the given data the equation we have is the following:
y=4/5x-3
The number which is multiplying the x is always the slope, therefore the of the line represented by the equation y=4/5x-3 would be 4/5.
Remember that the slope of a generic equation would be the m.
So, in this case the m would be 4/5
