X is directly proportional with y, so y=mx+b
Because of y=6 x=1, 6=m+b
Only you should do is to find any two numbers that their result is 6
Like m=2 b=4. y=2x+4
m=1 b=5. y=x+5 ...
Answer:
the answer is 210
Step-by-step explanation:
10×10=20+1=21, 21×10=210
Answer:
x = (y - b)/m
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First subtract b from both sides:
y = mx + b
y (-b) = mx + b (-b)
y - b = mx
Next, divide m from both sides:
(y - b)/m = (mx)/m
x = (y - b)/m
x = (y - b)/m is your answer.

2/3 = 9/y
cross multiply
2y = 9 * 3
2y = 27
y = 27/2
y = 13.5 or 13 1/2
6-1=5
5/5=1
D=1 would be the correct answer if that is what they are asking
