What is the best first step to find the slope and y-intercept when given an equation of a line?

When given a slope intercept form type of equation (y = mx + b), automatically, the value of m, which is the coefficient of x is the slope and the value of b, which is also known as the constant is the y intercept

But when given another type of form in an equation, always isolate y first for you to get a value of m and b

In y=mx+c, c is the y-intercept or make x=0.
