Find y if the point (-6,y) is on the line that passes through (-1,7) and (3,2).

The slope is

 

[ 2 - 7 ] / [ 3 - -1 ] =  -5 /4

 

 

Using the second point and the  slope to  write the equation of the line

 

 

y= -(5/4) (x -3) + 2

 

When x = -6

 

y = (-5/4) ( -6 - 3) +  2

 

y = (-5/4)(-9) + 2

 

y = 45/4  + 8/4

 

y =  53 / 4
