If the slope of BC is 1/2 what is the slope of AC

See Explanation

Step-by-step explanation:

The question is incomplete.

However, I'll answer base on the following assumptions.

1. AC and BC are parallel.

2. AC and BC are perpendicular

For (1)

Parallel lines have equal slopes.

So, AC = BC = ½

For (2)

Slope of perpendicular line is:

m1 * m2 = -1

Take m1 as slope of BC

So, we have

½ * m2 = -1

Solve for m2

m2 = -1/½

m2 = -1 * 2

m2 = -2

Hence, the slope of AC is -2

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
