find the the slope

Question

Find the slope of the line y = -x + 3.

is the answer -1 or is there not enough information

Answer 1

The slope-intercept form of the equation of a line is:  y=mx + b

     where m=slope

       and the point (0,b) is the y-intercept (the place the line crosses the y-axis at x=0)

 

For the line:

   y = -x + 3

   y - (-1)x + 3       [this is y = mx + b]

m = -1       [the slope]

the point (0,3) is the y-intercept
