*Write the equation in slope-intercept form > "y = mx + b"
First: subtract "5x" from both sides (when you move a variable/number to the opposit side, always use the opposite sign)....
5x - 5x + 3y = 4 - 5x
3y = 4 - 5x
Sec: isolate "y" on one side > divide every term by "3"....
3y/3 = 4/3 - 5x/3
y = 4/3 - 5x/3
Third: the equation has to be in alpha descending order in which, the "x" variable is first....
y = -5x/3 + 4/3
*The slope is a fraction/whole number beside the x-variable. In this case the slope = -5/3

It is very very easy!.
5x + 3y =4 thus y=(-5/3)x + (4/3)
so the slope of the function is (-5/3).
you can solve it with derivative very easier than it.

how I like to do problems like this by putting the formula into slope-intercept form (y=mx+b, where m is the slope and b is the y-intercept)
so, to do that, all you have to do is solve for y, and whatever ends up as the coefficient of x is the slope.
5x+3y=4
3y=-5x+4
y=-5/3x+4/3
so, the slope is -5/3.

5x + 3y = 4
3y = -5x + 4
y = (-5/3)x + (4/3)
Slope is the coefficient of the x variable when the standard slope-intercept form of the line ( y = mx + b ) is used.
Here your slope = (-5/3)

Rearrange to the form y = mx + c
5x + 3y = 4
3y = -5x + 4
y = -5/3x + 4/3
m is the gradient
i.e. -5/3

write it as y= mx +n.Then m is the slope
y=-5/3 x +4/3 So the slope is m= - 5/3
