Question

If the equation y = 3x + 2 is changed to y = -3x + 2, how will the graph of the line change?

Answer 1

The x-intercept will stay the same, but the slope will be flipped from +3 to -3. This means that, instead of being pointed from bottom left to top right, it will go from top left to bottom right (but going through the same point (0,2))

Answer 2

thanks, so how many units will it shift?

Answer 3

it doesn't shift
