Y=mx+c where m is the gradient.
If the equation is perpendicular is -
Use y-y1=m(x-x1)
and you should get
y+1=-
(x+4)
4y+4=-3x-12
y=-<span>

Answer: 14th floor
Step-by-step explanation:
20 - 11 + 5 = 14
Answer:
-11 1/4
Step-by-step explanation:
Given,
y = -3x+1 (EQ1)
y = 2x-4 (EQ2)
Equate EQ1 and EQ2
EQ1 = EQ2
-3x+1 = 2x-4
-3x-2x = -4-1
x = 1
y = -3x+1
y = -3(1)+1
y = -3+1
y = -2
(1, -2)
~B
C. 10r-3
Because 2r+5=7, the minus 6 and 7 which gives you 1 then minus 4 and 1 witch is 3 then you do 10r-3 and it will get you to 2r+5=7 again. I hope this helped!
