If it has to be perpedicular to y = x, then the slope has to be -1/x because perpedicular slope is the opposite reciprocal. Now plug what you know into the point slope formula.
y - 2 = -1/1 (x - 4)
***** Since -1/1 is the same as -1, it can be rewritten as -1. ****************
y - 2 = -1 (x - 4)
Now distribute -1 times x and -4.
y - 2 = -x + 4
Add 2 to both sides to get y by itself.
y = -x + 2
Your answer should be:
y = -x + 2
To find the slope, we can use the formula m = y change/x change. Since we already have 2 points, we can subtract the second coordinates from the first ones.
1. (-18-(-18))/(15-6) = 0/9 = 0. m=0x
2. (16-12)/0-8) = 4/-8 = -1/2. m = -1/2x
Hope this helps.
About 8 meters since the space is smaller than the 12 meter space
Answer:
y = 4x - 2
Step-by-step explanation:
slope = 4
y -6 = 4 ( x- 2 )
distribute the 4 to ( x - 2 )
y - 6 = 4x - 8
add 6 to both side
y = 4x - 2
Hopefully this helps you understand this concept.
