Given the point (4, 5) and the slope of 6, find y when x = 24.

An equation for the line that passes through the point (4, 5) with a slope of 6 can be found using the point-slope formula:  y - y1  =  m(x - x1).

In this problem, m = 6, x1 = 4, and y1 = 5:

      y - 5  =  6(x - 4)

     y - 5  =  6x - 24

     y  =  6x - 19

If x = 24:

     y  =  6(24) - 19

     y  =  125
