Find an equation for the linear function which has y-intercept (0,−6) and x-intercept (11,0).

For this case we have an equation of the form:
 y = mx + b
 Where,
 The slope of the line is:
 m = (y2-y1) / (x2-x1)
 m = (0 - (- 6)) / (11-0)
 m = 6/11
 The value of b is given by:
 b = -6
 Substituting values we have:
 y = (6/11) x - 6
 
 An equation for the linear function is:
 y = (6/11) x - 6
