She has teacher licensure for high school math as well as a graduate certificate in Online Teaching and Instructional Design. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. We can calculate the x-intercept by putting y as 0. Select one of the options Type a linear equation (Ex: 3x - 2y = 3 + 2/3 x) = The vertex of the quadratic equation is located at (1.00, -6). The slope intercept equation can be represented as: y = mx + b. But, when a point is on the x-axis, we recognize at once that y coordinate will be equal to zero (0) and then we have only one unknown, which is the x intercept. We just have to put the value of y as 0 in the equation of the curve. So, to find the y-intercept, we substitute \(x=0\) into the equation..
