Greetings!
To find the slope and y-intercept of this line, we need to rearrange the equation into slope y-intercept form:

To accomplish this, let's first isolate the y variable:

First, add 7x to both sides:


Divide both sides of the equation by -4:



The slope (m) is equal to:

The y-intercept (b) is equal to:

I hope this helped!
