A line is parameterized by x = 4 + 3t and y = 4 + 7t. (a) What part of the line is obtained by restricting t to nonnegative numbers? We get the part of the line to the left of and below the point (4,4). (b) What part of the line is obtained if t is restricted to −1≤ t ≤ 0? We get the part of the line to the right of and above the point (4,4). (c) How should t be restricted to give the part of the line to the left of the y-axis? NOTE: Enter an exact inequality or round to three decimal places.
