Hi,

Using the standard slope-intercept form for an equation of a line y = mx + b  where m is the slope and b the y-intercept.

Line through the point (-1, 2), parallel to the line –4x – 9y = -7 OR y+=+highlight%28-4%2F9%29x+%2B+7%2F9

New Line

 y = (-4/9)x + b

 2 = (-4/9)·-1 + b   |Using ordered pair (x,y):(-1,2)  to solve for b

 14/9 = b

 y = (-4/9)x + 14/9
