For lines to be parallel, the slopes have to be the SAME.
For lines to be perpendicular, the slopes have to be the exact opposite. (opposite sign and number)
For example(perpendicular):
slope is 2
the perpendicular slope is -1/2
slope is -4/5
the perpendicular slope is 5/4
12. line a and b are perpendicular
13. Line a: y = 3/5x + 1
Line b: y = 3/5x - 2/5
Line c: y = 4/6 + 5/3x
line a and b are parallel
14. Line a: y = 3x + 6
Line b: y = 6 - 3x
Line c: y = 2/3x + 6
Neither, none of them are parallel or perpendicular
15. Line a: y = -2/3 + 4/3x
Line b: y = -1/4 - 3/4x
Line c: y = 5 + 3/4x
line a and b are perpendicular
Answer:
$15.00
Step-by-step explanation:
Suppose 1 rose bush costs r dollars,
Suppose 1 geranium costs g dollars.
Here are 2 equations:
1)6r+14g=146
3r+7g=73
2)r+7g=57
r=57-7g
Put 2) in 1)
3(57-7g)+7g=73
171-21g+7g=73
98=14g
g=7
r=8
7+8=$15.00

Answer: <em>y = 3/4 x + 8</em>
Step-by-step explanation: First you must find the slope of line k.
<em>y2 - y1</em>
<em>m = -----------</em> <em>The slope is 3/4</em>
<em> </em><em>x2 - x1</em>
Since the two lines are paralell you know that line h has the same slope.
Next you must find the y-intercept by replacing x and y with the values given by the point.
<em>y = 3/4x + ? -----> 12 = 3/4(4) + ?</em>
<em> 12 = 3 + 8</em>
The y-intercept is 8
Your equation for line h is <em> </em><em>y = 3/4 x +8 </em>
<em></em>
