What is the value of y at the x-intercept and why? ...At the x-intercept, the value of y = 0. This means that the graph of a given equation crosses the x-axis at some given point (b, 0).
What is the value of x at the y-intercept and why?...At the y-intercept, x = 0. This means the graph of a given equation crosses the y-axis at some given point (0, b).
Is there any difference between solving a system of equation by the algebraic method as opposed to the graphical method? Explain. ...Using the algebraic method allows us to find the solution to a systems of equations without having to make a picture of the equations on the xy-plane. By graphing, we can see where the equations cross, touch or meet each other on the xy-plane. Where they touch, meet or cross each other is the place of solution. By the way, we can also use matrix algebra to solve systems of equations.
