Question 480617
A line that passes through (-2, 7) and is parallel to the line 2x - y = 1 has equation?  
====================
Putting in standard y = mx + b form we have y = 2x - 1
Parallel lines have the same slope, so the equation of our line is y = 2x + b
Since (-2,7) lies on the line we can use this to determine the y-intercept:
7 = 2(-2) + b
This gives b = 11
So the equation is y = 2x + 11
