Answer: 
Step-by-step explanation:
The equation of the line is Slope-intercept form is:

Where "m" is the slope and "b" the y-intercept.
The slopes of perpendicular lines are negative reciprocal.
Then, if the slope of the first line is -3, the slope of the other line must be:

Substitute the point (3,4) into the equation and solve for b:

Then the equation of this line is:

Answer: tan62 = 10/x
Step-by-step explanation: Let me know if you need an explanation.
For the answer to the question above, A person drives north 6 blocks, then drives west 6 blocks. the displacement is a straight line from the starting point to the finish in <span>8.49 blocks</span> in a Northwest <span>direction.
The Solution:
</span>A^2+B^2=C^2
6*6+6*6 = sqrt(72)
16 only goes into 20 once
