What is the equation of a line that passes through the points open paren 3 comma 6 close paren and open paren 8 comma 4 close paren ?

The slope through (3, 6) and (8, 4) is (4 − 6)/(8 − 3) = −2/5. Substitute (3, 6) into y = mx + b: 6 = (−2/5)(3) + b, so b = 36/5. The equation is y = −2/5x + 36/5, choice B.
