X and y intercept formula. Since the slope of a horizontal line is 0 the general formula for the standard form equation y mx b becomes y 0x b y b. This y value is therefore also the y intercept. The y intercept is the place where the line crosses the y axis and the x intercept where the line crosses the x axis.
In general you can skip parentheses but be very careful. Click the blue arrow to submit and see the result. When you want the x intercepts x0.
For simple problems it is easy to find the x intercept by looking at a graph. Where the graph of an equation crosses the y axis. A linear equation has the form y mx b where m and b are constants.
Slope intercept form formula for the equation y mx b m is the slope of the line that is multiplied by x and b is the y intercept or we can say the point where the line will cross the vertical y axis. Find the intercepts of y x 2 4. Set x0 then solve for y.
If the equation is written in the slope intercept form plug in the slope and the x and y coordinates for a point on the line to solve for y. The equation can be in any form as long as its linear and and you can find the slope and y intercept. The x intercept is the point at which the graph crosses the x axisat this point the y coordinate is zerothe y intercept is the point at which the graph crosses the y axisat this point the x coordinate is zero.
The x intercept is the point where the line crosses the x axis. You can find the exact point of the intercept by solving algebraically using the equation of the line. E3x is e3x and e3x is e3x.
To find the y intercept using the equation of the line plug in 0 for the x variable and solve for y. If you dont know the slope calculate it by dividing the rise of the line by the run. The calculator will find the x and y intercepts of the given function expression or equation.
Alsosince the line is horizontal every point on that line has the exact same y value. To determine the x intercept we set y equal to zero and solve for x. This is a sensible equation that can also be named as the.
Where the graph of an equation crosses the x axis. In general you can skip the multiplication sign so 5x is equivalent to 5x. The intercepts of a graph are points at which the graph crosses the axes.
The slope and y intercept calculator takes a linear equation and allows you to calculate the slope and y intercept for the equation. Set y0 then solve for x. The equation of a horizontal line is y b where b is the y intercept.
To find the intercepts.
