Hi,         

the standard slope-intercept form for an equation of a line: y = mx + b  

where m is the slope and b the y-intercept.  



Using the point-slope formula, m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29

 (5,2) and (0,-9)

  m = -9 - 2  /0-5 = -11/-5 = 11/5

  m = 11/5

 y = (11/5)x + b Using ordered pair Pt(0,-9) to solve forb

 -9 = b

 y = (11/5)x -9
