Samantha drew a picture of her house. She used the scale 1 inch : 2.5 feet. The house in her picture is 20 inches long. What is the length, in feet, of the actual house?

20ft
25ft
50ft
75ft

The answer is 50 feet. If 1in = 2.5 ft, then 20in is 50 ft.

One unique triangle, because those angles add up to 180, and that's how many degrees there are in one triangle.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
