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.

Therefore, we can substitute:

#color(red)(-1.5)# for #color(red)(m)#

#color(blue)(-0.25)# for #color(blue)(b)#

Giving:

#y = color(red)(-1.5)x + color(blue)((-0.25))#

Or

#y = color(red)(-1.5)x - color(blue)(0.25)#

Or

#y = color(red)(-3/2)x - color(blue)(1/4)#
