Step-by-step explanation:
BD = DC = 1/2 BC ---> AD is median ( because in equilateral triangle altitude equals to median )
so, therefore
AB = 18 (given)
BD = 1/2 BC
BD = 1/2 × 18
BD = 9
AB² = AD² + BD² ---( by pythagoras theorm)
18² = AD² + 9²
324 = AD² + 81
324 - 81 = AD²
243 = AD²
then,
AD = √243
AD = 15 58

Answer:
Option C) y + 4 = x
Step-by-step explanation:
We are given the following information in the question:
Line AB goes through the points A (0, –4) and B (6, 2).
We can use the two-point form of equation of straight line.
The equation of line is given by:
where, is the point through which the line passes.
The equation of line is:
Thus, the equation of line AB is given by Option C) y + 4 = x
