Answer:

See a solution process below:

Explanation:

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.

Substituting the slope and #y#-intercept given in the problem allows us to write the equation as:

#y = color(red)(1/2)x + color(blue)(-3)#

#y = color(red)(1/2)x - color(blue)(3)#
