The y-intercept of ƒ(x) is indicated by the red dot at (x=0, y=1). In analytic
geometry, using the common convention that the horizontal axis represents a ...
Because functions associate x valu...
To find the y-intercept, we substitute 0 for x in the equation, because we know
that every point on the ... of 0. Once we do that, we can solve to find the value of y.
Jul 31, 2011 ... With that in mind, what value is y always going to be on the x-intercept? No
matter where you are on the x-axis, y's value is 0, that is a constant.
To find an x-intercept, let the value of y in the equation be equal to zero. ... A
horizontal line (other than y = 0) will not have an x-intercept. The line y = 0 is
An old video of Sal where he draws the line y=3x-9 by finding its x- and y-
intercetps. ... When you think x-intercept, you say, OK, that means my y-value is 0.
Slope is the ratio of the change in the y-value over the change in the x-value. ... if
you know the equation, the y-intercept is the solution to the equation when x = 0.
... the x and y values of a point on the line into the equation, you will get a true ...
The relationship between the roots and the x-intercepts of a graph. ... At the x-
intercept -- on the x-axis -- y = 0. The y-intercept is that value of y where the graph
You may think of this as a point with y-value of zero. To find the x-intercepts of an
equation, let y = 0 then solve for x. In point notation, it is written as ( x , 0 ).
At the X intercept, the graph line is touching the X axis, and thus the Y value at ...
The Y intercept is found by letting x = 0 and finding the corresponding value of y.
... This is true because substituting -3 for x and -2 for y reduces the equation to ...
The point in which the graph crosses the x-axis is called the x-intercept and the ...
The x-intercept is found by finding the value of x when y = 0, (x, 0), and the ...
