Graph y equals 2x plus 1?

Answer 1

y = 2x + 1 1. Make a table: x = -2; y = -3

y = 2x + 1

y = 2(-2) + 1 = -4 + 1 = -3 x = -1; y = -1

y = 2x + 1

y = 2(-1) + 1 = -2 + 1 = -1

x = 0; y = 1

y = 2x + 1

y = 2(0) + 1 = 0 + 1 = 1 x = 1; y = 3

y = 2x + 1

y = 2(1) + 1 = 2 + 1 = 3 x = 2; y = 5

y = 2x + 1

y = 2(2) + 1 = 4 + 1 = 5 2. Plug the points (-2, -3), (-1, -1), (0, 1), (1, 3), and (2, 5) in a xy-coordinate system. 3. Draw a line which passes through those points. Thus, the line drawn is the graph of the function y = 2x + 1
