x+y=-3 Change to slope-intercept form y=-x-3y-intercept = -3 Plot point (0,-3)Slope = coefficent of x = -1 Slope = Rise/run = Y/X From 0,-3 move down -1 and to the right 1 Or move up one and to the...
If you can draw two points of this line, you can simply use a ruler lined up with the two to draw the line. Let's look at two easy points, x=0 and x = 1 y = 3 +0 = 3 y = 3 + 1 = 4 Thus we know at...
all graphs of the form y=mx+c are simple to graph. SImpley notcice that it is a straight line, with gradiant m, and y-intercept of c.
So your example gives us a graph with a gradiant of -1 going...
