Solution 1
Equation of any straight line in the form y = mx + c, where slope = m(co-efficient of x) and y-intercept = c(constant term)
x= 5y - 4
x= 5y - 4
5y = x + 4
y = `(x + 4)/(5)`
y = `(1)/(5) x + (4)/(5)`
Therefore,
slope = co-efficient of x = `(1)/(5)`
y-intercept = constant term = `(4)/(5)`

Solution 2
Equation of any straight line in the form y = mx + c, where slope = m(co-efficient of x) and y-intercept = c(constant term)
x = 5y - 4
x = 5y - 4
5y = x + 4
y = `(x + 4)/(5)`
y = `(1)/(5) x + (4)/(5)`
Therefore,
slope = co-efficient of x = `(1)/(5)`
y-intercept = constant term = `(4)/(5)`.
