The equation of line in slope intercept form is # y= 5/4x -63/4 #

Explanation:

Let the equation of line in slope intercept form is # y=mx+b#

where #m# is slope and #b# is #y# intercept.

Then the equation of line with a slope of #m=5/4 # is

# y= 5/4x +b # . Since the point # (3 , -12)# is on the line , it

will satisfy the equation. # - 12 = 5/4*3 +b or b= -12-15/4#

or #b = -63/4 #

Hence the equation of line in slope intercept form is

# y= 5/4x -63/4 # [Ans]
