Question

Which is the equation of a line that passes through (1,8) and (6,4)

Answer 1

Answer:

y = - $\frac{4}{5}$ x + $\frac{44}{5}$

Step-by-step explanation:

(6, 4)

(1, 8)

m = $\frac{8-4}{1-6}$ = - $\frac{4}{5}$

y - 4 = - $\frac{4}{5}$ ( x - 6 )

y = - $\frac{4}{5}$ x + $\frac{44}{5}$ ⇔ y = - 0.8x + 8.8
