Hi
graph the line containing the given pair of points and find the slope
Using the point-slope formula, {{{m =(y[2] - y[1])/(x[2] - x[1])}}}
(-1,7) and 
(2,4)   m = (7-4) / (-1-2) = 3/-3 = -1
y = -x + b  |Using ordered pair Pt(2,4) to find b
4 = -2 + b
 6 = b    |  y = -x + 6  OR standard form:  x+ y = 6
