Question 433097
Parallel lines have the same slope.  Therefore, the slope = 4.  Now we need to find the y-intercept.  
The slope of a line is determined from two points on the line (x1,y1), (x2,y2):
m = (y2-y1)/(x2-x1) [rise/run]
One of the points on the line is the y-intercept with coordinates (0,b), and the other point is (-3,5).  
Use the formula for the slope to find b:
m = 4 = (b-5)/(0+3) -> b-5 = 12, or b = 17
So the equation for the line is:
y = 4x + 17
