Scale factor help plz

The scale factor is 3/2 or 1 to 1.5

Step-by-step explanation:

Here, we want to find the scale factor of the first to the second

Since the triangles are similar, it follows that the corresponding sides are of equal ratio

So, we have the scale factor for the sides as;

6/4 or 9/6

= 3/2 or 1 to 1.5

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?
