• The farmer lost on average 5 strawberries for every 4 degree increase in temperature.

• When the weight of the strawberries increased by 4 grams, the temp decreased by 5 degrees

• When the temperature by 4 degrees, the strawberries lost on average 5 grams of weight.

On the coordinate plane in the image, triangle PQR is similar to triangle RST. The corresponding side lengths of triangle RST and triangle PQR are in the ratio of 3:1.

What is the equation of the line containing the points P and T.

Which of the following statments is TRUE of triangles FGH and HJK in the image.
