How do you graph #y= -5x-1#?

See explanation. Follow the method and you should get high marks (hopefully).

Substitute values for #x# and completing the calculation. In each case note the value for both #x# and #y# as 'matched pairs'. Use these 'matched pairs' (proper name: ordered pairs) to mark points on the graph paper. Most people say have two points but I suggest 3. The third acts as a check as all three should line up.

Mark points and draw a line through them extending it to the end of the squared area on the graph paper.

Label your axis and give a title to the graph This gives you extra marks for good communication.

Make your marked point very clear and label them. Include a small table showing your calculation for the points. Again; good communication = extra marks!

undefined To graph the equation y = -5x - 1, you can start by plotting the y-intercept, which is -1 on the y-axis. Then, use the slope of -5 to find additional points on the line. For each increase of 1 in the x-coordinate, decrease the y-coordinate by 5, and vice versa. Connect these points to draw the line.
