Answer:
The y-intercept of line is (-3)
Step-by-step explanation:
Given equation of line is given by y= 
The general equation of line is given y=mx+c
Where, m= slope of line
c= y-intercept of line
On comparing both the equation.
c=(-3)
OR
y-intercept is when x=0,
therefore,
y= 
y= 
y=(-3)
Thus, y-intercept of line is (-3)
Answer: 12.5
You start with the equations "2x +2y=38" and "6+x=y". By adding and subtracting in the second equation, you get "2x +2y=38" and "x-y=-6". When you multiply the second equation by 2, you get "2x-2y=-12."
subtracting the equations "2x +2y=38" and "2x-2y=-12" gets you to "4y=50", where you have to divide two sides by 4 and get "y=12.5"
