Answer:
Step-by-step explanation:
What we do know about parallel lines is that they have the same gradient
Therefore, m1=m2 implying that the other line has a gradient of two(2)
We then substitute the the general formula y=mx+c
where y=4(as shown in the question)
4=2*-2 + c
4=-4 + c
8=c
In conclusion the equation of that straight line is y=2x+8
