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.  Slope (-3/4)

  y = (-3/4)x + b  Using order pair Pt(4,-9) to solve for b

 -9 = (-3/4)*4 + b

 -6 = b

  y = (-3/4)x -6

graph of this line.  Note: m < 0, line slants to the left
