Y= -x on a graph passes through what quadrants?

Question

Please graph.

Answer 1

II and IV quadrants.

Answer 2

Slope - intercept form line equation is y = mx + b, where m is slope and b is y - intercept.

The line equation is y = - x.

Compare the equation with slope - intercept form : y = mx + b.

slope = - 1 and y - intercept is 0.

y - intercept is 0, so the line crosses the y - axis at origin (0, 0).

Using slope find the next point.

Slope = rise/run = - 1/1

Start at point (0, 0), move 1 unit down and 1 unit right, then plot the point (1, - 1).

Draw the lines through these points.

Observe the graph, the line y = - x passes through II and IV quadrants only.
