In the ratio 1 : 8, if x = 2, y = 16

Step-by-step explanation:

When X = 6, Y = 48

⇒The ratio of X  :  Y =  6  :  48

Now, the ratio 6 : 48 in its lowest form is 1   :   8

Now, when x = 2, then y  =  2 x 8    = 16

Hence, in the ratio 1 : 8, if x = 2, y = 16

is it 35

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
