A number is equal to the sum of half a second number and 3. The first number is also equal to the sum of one-quarter of the second number and 5. The situation can be represented by using the graph below, where x represents the second number. On a coordinate plane, a line goes through (0, 3) and (8, 7) and another line goes through (0, 5) and (8, 7). Which equations represent the situation? y= one-half x 3 and y = one-fourth x 5 y = 3 x one-half and y = 5 x one-fourth y = 2 x 3 and y = 4 x 5 y = 3 x 2 and y = 5 x 4.
