See the solution process below:

Rewrite the equation as:

#y = x#

The slope-intercept form of a linear equation is: #y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b)# is the y-intercept value.

Putting our equation into this form gives:

#y = color(red)(1)x + color(blue)(0)#

Therefore:

The slope is #color(red)(m = 1)#

The y-intercept is #color(blue)(b = 0)# or #(0, 0)#
