Y = 4x - 5 and (3,4) (7, 3) A. parallel B. perpendicular D. neither
s344n2d4d5 [400]

Answer:

<em>The lines are perpendicular. </em><em>Option B.</em>

Explanation:

<u>Equation of the Line</u>

One of the characteristics of the line is its slope. It can be determined in two ways:

* From the equation y=mx+b, the m is the slope. The given equation is y=4x-5. Thus, the slope of this line is m=4.

* Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

The points are (3,4) and (7,3), thus the slope is:

\displaystyle m=\frac{3-4}{7-3}=-\frac{1}{4}

A. For two lines to be parallel, their slopes must be equal. Since m1=4 and m2=-1/4, the lines are not parallel. Incorrect

B. For two lines to be perpendicular, their slopes must meet the condition:

m1*m2=-1

4*(-1/4)=-1

Both lines are perpendicular. Correct choice

D. Since choice B. is correct, this cannot be true. Incorrect
