![]() ![]() Solving systems of equations, or in economics when computing consumer and producer surpluses. The intercepts of a line provide an excellent graphical intuition of what the line is doing, and they have direct applications when Free math problem solver answers your algebra, geometry. write down the equation of a circle in standard form : ( x- b ) 2 + ( y k ). If the y value at which the line crosses the y-axis is \(y_\right)\).Īnother calculation you may be interested too is the one using our x-intercept calculator, which is the point where the The slope-intercept form is y mx+ b y m x + b, where m m is the slope and b b is the y-intercept. calculator to see which one matches the given graph. Free math problem solver answers your algebra. It depends a bit on the convention that you use. The slope-intercept form is y mx+ b y m x + b, where m m is the slope and b b is the y-intercept. ![]() X = 0, we get \(y = n\), and we know \(x = 0\) is the point where the graph crosses the y-axis Is the y-intercept a number or a pair (x, y)? Why? because \(y\), as a function of \(x\) is \(y = mx + n\). You already know that the y-intercept is \(n\). The ideal way, though, it is calculate the y-intercept algebraically. How do you find y-intercept with the slope? That way you can then get an idea at least of the approximate value of the Line and more or less estimate where it crosses the y-axis, which is the finding the y-intercept on the graph method. Often times, you can eyeball the graph of the The way you compute the y-intercept will depend on how you have specified the line.
