2/3 = 9/y
cross multiply
2y = 9 * 3
2y = 27
y = 27/2
y = 13.5 or 13 1/2
Do you want the exact form or decimal form?
So your going to want to place 1/3 first and put it closer to the front but not right at the beginning. Then put 1/2 right in the middle. Finally put 7/8 close to the end.
What question am I supposed to answer by 9 o'clock.
So confused!!
Y= kx+b, k-slope, b-intercept
so
2=k*1+b
7=k*2+b
12=k*3+b
17=k*4+b
solve these two equation:
2=k*1+b
7=k*2+b
second minus first is 7-2=2k-k+b-b
5=k,
so we know k=5
put this in any equation 2=5*1+b
b=2-5
b=-3
check this in
12=5*3-3 - right
17=5*4-3 - right
Answer: y=5x-3
