keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

so therefore

so we're really looking for the equation of a line whose slope is 2/3 and passes through (-4 , -3)

Answer:
.111 11.1%
2/5 2:5

Step-by-step explanation:
His salary would be 474,720$
Answer:
60 degrees
Step-by-step explanation:
The sum of the angles in a triangle are 180 degrees. The angles look the same size, so divide 180 by 3, and you get 60 degrees
Let point C has coordinates
Consider vectors

Since the ratio AB to BC is 1:4, you have that

Find
and 

Answer: C(4,-6)
