Question 636684

How do I graph y=-x-10


y = mx + b, so from y = - x - 10, slope, or m = - 1, and y-intercept = - 10


Since the y-intercept = - 10, coordinates of y-intercept = (0, - 10). You can start from this coordinate point, and plot other points by applying the slope of - 1. The rise/run fractions can either be {{{(- 1)/1}}}, or {{{1/- 1}}}. After getting the amount of points needed, draw a line through them,


OR


Just simply get the y, and x-intercepts, and join the points.


y-intercept is the point where the x-value = 0. This is (0, - 10)


The x-intercept is the coordinate point on the x-axis where the y-value is 0. Plugging 0 for y into equation gives us:


y = - x - 10


0 = - x - 10


x = - 10


This means that the x-intercept is at (- 10, 0)


Join the two coordinate points, (0, - 10), and (- 10, 0) and you have your graph.
