Hi

point-slope formula, y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29, equation of the line to find the equation of a line with slope m and P%28x%5B1%5D%2Cy%5B1%5D%29 on the line  

line that has a slope of -5 (-5/1) and goes through the point (-4, 9)

 y - 9 = -5(x+4)

OR

 y = -5x -11

Note: as y increases/decreases by 5, x value changes by 1 in the other direction
