Here we use the general format y=mx + b (sometimes written y=mx + c). b tells us where the graph crosses the y axis. That gives us our first point for the graph. m is the slope.

Estimating Points on a Graph 1 Determine the function. Get the function of the form like f ( x ), where y would represent the range, x would represent the domain, and f would

Explanation: The equation y = − x can be written in slope intercept form as. y = − 1 1 x +0 making the y intercept at (0,0) and the slope − 1 1. Begin by graphing the y intercept at
