Line is y = 4x - 9
this has a slope of 4 (from y = mx + b the slope intercept form).
Infinite parallel lines have same slope, giving y = 4x + n (n any number except -9 which is original line)
Specific parallel line passing through (-2, 4) has equation y = 4x + c, and we substitute point values to find c:
(4) = 4(-2) + c => 4 = -8 + c => c = 12
hence required line is y = 4x + 12
