The length of a cell phone is 1.61.6 inches and the width is 4.64.6 inches. The company making the cell phone wants to make a ne
w version whose length will be 2.162.16 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Step-by-step explanation: Once you subtract from both sides, in order to solve for y (as the equation needs to be in the slope-intercept form, otherwise known as ), you end up with , which is the right answer. It is the correct answer because the y-intecept shown in the equation matches what is on the graph, in addition to the fact that the slope is just .
