Given 4x − 8y = 8:
transform the equation into slope-intercept form.
find the slope and y-intercept of the line.
find the equation, in point-slope form, of the line that is perpendicular to this line and passes through the point.

(b).∠ABC is bisected by ray BD.

(c) BC = One-half of AC

(e) 2 ∠DBC = ∠ABC

Step-by-step explanation:

Here ray AC and ray BD is perpendicular to each other.

Thus, Option (a) is not true as ∠DBC is not bisected by any ray.

Option (b) is correct.

Option (c) is also correct as B is the mid-point of AC.

Option (d) is also incorrect as length of line segment DB and line segment BC can be different.

Option (e) is also correct.
