what is the slope of the line

Question

what is the slope of the line y=10

Answer 1

zero

The slope of a horizontal line = 0

y=10 is a flat horizontal line, with y-intercept of 10

in slope intercept form the equation is

y=mx + b where m=0 and y= 10

y= 0(x)+10

y= 0 + 10

y= 10

Answer 2

;y=10 is a horizontal line. Therefore it's a no slope line.
