Answer: m = -4
Step-by-step explanation: If they have the same slope, the lines will be parallel.
Hope this helps!
Step-by-step explanation:
Hey there!
Answer: -4
The slope of the lines which are parallel to eachother is equal.
{i.e M1(slope of 1st equation) is equal to m2 (slope of 2nd equation)} (M1=M2)
Therefore, the slope would be -4.
