5. The students in Suzanne's school are painting a rectangular mural outside the building that will be 15 feet by 45 feet. A. Write the unit rate for the proportional relationship between lengths on the mural y and lengths in the scale drawing x. 6. The students at Suzanne's school are also going to paint a smaller mural inside the building. A scale drawing of the mural is shown on the grid. IT B. MP Model with Mathematics Write an equation that relates x and y. The diagonal of the scale drawing is approximately 6.3 units. Estimate the length of the diagonal of the mural. A. Redraw the inside mural on the grid using a scale of 1 unit:1 foot. A Ⓒ Houghton
