SOLUTION: Why is it true that at the x-intercept, the value of y is 0, and at the y-
intercept, the value of x is 0? Please give 1 or 2 examples please? I would like to
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 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.
Sal determines the x-intercept of a linear equation from a graph. ... have to figure
out what x value, when y is equal to 0, will have this equation be true. So we ...
Take a closer look, and you'll see that the y-axis is also the line "x = 0". ... an x-
intercept is a point in the equation where the y-value is zero, and; a y-intercept is
Mar 5, 2007 ... y = -|x + 5| Let x = 0 y = -|0 + 5| y = -|5| y = -5 so the y- intercept is (0,-5)
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
The graph of a quadratic equation in two variables (y = ax<sup>2</sup> + bx + c ) is called a ...
but irrational (radicals) then we need to approximate their values and plot them.
... We can use this fact to find the y-intercepts by simply plugging 0 for x in the ...
Ex: Find the equation of the tangent line of y = x<sup>3</sup> at x = 2 ... Similarly, the x-
intercept is the x-value when y = 0, where the graph crosses the x-axis. To find
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
