#y=-14/25x+69/250#

A general equation to model a linear function is:

#y=mx+b#

where:
#y=#y-coordinate
#m=#slope
#x=#x-coordinate
#b=#y-intercept

Assuming that your point is #(23/5,-23/10)#, substitute your known values into the equation and solve for #b#, the y-intercept:

#y=mx+b#

#-23/10=-14/25(23/5)+b#

#-23/10=-322/125+b#

#-23/10+322/125=b#

#(-23(25)+322(2))/250=b#

#(-575+644)/250=b#

#b=69/250#

#:.#, the equation is #y=-14/25x+69/250#.
