Answer:
The correct answer would be C
Step-by-step explanation:
If you were to input the X and Y values of the two coordinates into equation C, you will see that the equation would be true for both coordinates, meaning that (4, -3) and (5, 0) are both points that are on the line Y + 3 = 3(X - 4).
Given that 2 similar signs have a scale factor of 5:3 and the larger sign is 45 ft, then the smaller sign will have the height given by:
scale factor=(height of large sign )/(height of smaller sign)
let the height of smaller sign be x, plugging in the values we get:
5/3=45/x
solving for x we get
3/5=x/45
hence
x=3/5×45
x=27 ft
The height of smaller sign will be 27 ft
