#y = color(red)(3)x + color(blue)(23)#

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.

We can transform this equation to slope-intercept form by solving for #y#:

#y - 11 = 3(x + 4)#

#y - 11 = (3 xx x) + (3 xx 4)#

#y - 11 = 3x + 12#

#y - 11 + color(red)(11) = 3x + 12 + color(red)(11)#

#y - 0 = 3x + 23#

#y = 3x + 23#
