What is the slope of the line represented by the equation y = -x? 

Solution:

We will use the concept of the slope-intercept form of a straight line to find the required slope.

Let us consider a general slope-intercept form of the equation of the straight line that is y = mx + c

In the general equation of the line, m is known as slope, and c is known as the y-intercept of the straight line.

On comparing the equation y = -x with the general equation of staright line we can easily say that m (slope) = -1 and c (y-intercept) = 0

Hence, the slope of equation y = -x is -1.

What is the slope of the line represented by the equation y = -x? 

Summary:

-1 is the slope of the equation of the line given by y = -x.
