Which lines are perpendicular?
makkiz [27]

Given:

Line A: y=\frac{1}{2} x+2

Line B: y=\frac{-1}{2} x+7

Line C: y=2 x+4

Line D: y=\frac{1}{2} x+\frac{5}{4}

To find:

Which lines are perpendicular

Solution:

General equation of a line:

y = mx + c

where m is the slope and c is the y-intercept.

Slope of line A = \frac{1}{2}

Slope of line B = \frac{-1}{2}

Slope of line C = 2

Slope of line D = \frac{1}{2}

<em>Two lines are perpendicular if their slopes are negative reciprocal of one another.</em>

$\Rightarrow m_1=\frac{-1}{m_2}

$\frac{-1}{2}=-(-2)=2

Negative reciprocal of \frac{-1}{2} is 2.

Therefore line B and line C are perpendicular lines.

What is the solution to this set of equations?
Vesnalui [34]

Answer:

(3,0)

Step-by-step explanation:

2x + 2y = 6  divide thru by 2 and you get  x + y = 3  

Name   x + y = 3  equation (1) and  x - y = 3 equation (2)

Add equations (1) and (2)  

 (1)   x+ y = 3

 (2) <u> x - y = 3   </u>  

        2x = 6

          x = 3  

Substitute x = 3 into equation (1).  So, 3 + y = 3

                                                                    y = 0
