Knowing that f(3) = 6 and f(-8) = 10 gives you two points on the line:

(3, 6), (-8, 10)

The slope between these two points is:

The equation of the line, in slope-intercept form, is y = mx + b.

Substituting -4/11 in place of m, and using the point (3, 6) gives:

6 = (-4/11)(3) + b

b = 6 + (4/11)(3)

b = 78/11

The equation is then:
