Find the slope of the line 7x-4y=10

The slope is

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

so

Convert to slope intercept form

Isolate the variable y

The slope is

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
