1) For Equation One, Plot the Y intercept, then slope: In the equation y = x-1, plot a point at (0,-1). From that point go up one and right one, plot the point. Draw your line.2.) For equation two, Plot the y intercept, then slope. In the equation y = -x +1, plot a point at (0,1). From that point go down one and right one, plot the point. Draw your line.3.) Determine at what point these lines intersect? State your solution.

y = mx +b where m is the slope, and b is the y intercept.For the following Equations:y = x - 1m, the slope, is 1, the y intercept is -1y = -x +1m, the slope, is -1 and the y intercept is 1
