Answer:
3x-2y=-4 is the equation of the slope intercept line.
Step-by-step explanation:
The passing through point (4,8)=(x1,y1)
Slope(m)=3/2
the equation is
or (y-y1)=m(x-x1)
or (y-8)=3/2(x-4)
or 2y-16=3x-12
or 2y-3x=16-12
or 2y-3x=4
or -(3x+2y)=4
or 3x-2y=-4
This is the Final equation of that line..
Answer:
