Answer: 
Step-by-step explanation:
Equation of the line given ;
To find the slope of the line we will make y the subject of formula , that is
Therefore ; the slope = 
Two lines are said to be parallel if they have the same slope
This means that the slope of the second line =
Using the formula 
to find the equation of the line , we have
4 would be the only possible answer bc 7 x 4 = 28 and 28 - 12 = 16.
Step-by-step explanation:
The y-intercept is the value where the line crosses the y-axis.
