Graph the proportional relationship y = - 2x by plotting points. (1 point)

Answer 1

To graph the proportional relationship y = -2x, we can start by choosing a few values for x and then finding the corresponding values of y.

Let's choose x = -3, -2, -1, 0, 1, 2, 3.

When x = -3, y = -2(-3) = 6 => (-3, 6)
When x = -2, y = -2(-2) = 4 => (-2, 4)
When x = -1, y = -2(-1) = 2 => (-1, 2)
When x = 0, y = -2(0) = 0 => (0, 0)
When x = 1, y = -2(1) = -2 => (1, -2)
When x = 2, y = -2(2) = -4 => (2, -4)
When x = 3, y = -2(3) = -6 => (3, -6)

Plotting these points and connecting them with a straight line, we get the graph of the proportional relationship y = -2x. The line will pass through the origin (0,0) and have a negative slope of -2.
