How To Write X Intercept
A parabola with two x intercepts.
How to write x intercept. To find the x intercept set latex y 0 latex. The x intercept goes into the x slot and 0 is what is in the y place. An ordered pair is written in the form x y displaystyle x y and gives you the coordinates for the point on the line. The point where the line touches the y axis is called the y intercept. Take a look at the graph below.
Use your finger to trace the green parabola in the image in the next section. Well the respective intercepts go into their respective places. At this point the x coordinate is zero. C is the intercept of the line. Write the ordered pair for the x intercept.
If we can find the points where the line crosses the x and y axis then we would have two points and we d be able to draw a line. X intercept is the value of x when y 0 make y 0 and the equation becomes 2x 20 solve for x to get x 10 the ordered pairs from this would be. The x intercept formula of a line ax by c is large x frac c a the x intercept formula of a line in the slope intercept form y mx c is large x frac c m where m is the slope of the line. 3 x research source the first number of the pair is the point where the line crosses the x axis the x intercept. You can put this solution on your website.
The answer should be an ordered pair. Notice that your finger touches the x axis at 3 0 and 4 0. Since the x intercept is 4 and the y intercept is 3 this means that the line goes through the points 4 0 and 0 3. Answer by jim thompson5910 35256 show source. The x intercept formula of a line in the point slope form y b m x a is large x frac b m a.
We have an x intercept and a y intercept. On the next to the last step where you are dividing both sides by 3 you should be dividing by 3 instead. Write an equation for the line with x intercept 4 and y intercept 3. For example lets find the intercepts of the equation latex y 3x 1 latex. The x intercepts are points where the graph of a function or an equation crosses or touches the x axis of the cartesian plane.
