Line l has a y-intercept of 2 and contains the points (a,a) and (2a,12). If a is a positive constant, what is the slope of line l?

1 answer

just use the definition of slope.

slope of line = (12 - a)/(2a - a)
= (12-a)/a

since you also know the y-intercept is 2, the equation would be

y = ((12-a)/a) x + 2
