Hi,

Using the point-slope formula, 

(-7, 0) and 

(4, 2)  m = -2/-11 = 2/11

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.  

 y = (2/11)x + b   |Using ordered pair (4,2) to solve for b

 2 = (2/11)*4 + b

14/11 = b

    9/6 = 3/2 = b

 y = (2/11)x + 14/11
