What does it mean when there is no x intercept?
If the value of the discriminant is zero, there is one real solution for x, meaning the graph of the solution has one x-intercept. If a negative number is inside the square root, there are no x-intercepts.
What is the equation of the line if it has no x intercept?
The x-axis is defined by the equation y=0x+0. Since we see that our equation and that of the x-axis have the same slope, they will never intersect. So, to answer your question, any equation of the form y=b will have no x-intercept, except y=0, which will have infinitely many intercepts.
What is the equation if there is no y-intercept?
Explanation: If a line has no y intercept, then it can only be parallel to the y axis and therefore has an equation of the form x=a for some constant a .
Can a function have no y-intercept?
In fact, any time a function is undefined at 0, it will have no y-intercept.
What is the formula for finding y intercept?
y-intercept = b = B/C. Alternatively, To find the x-intercept, substitute y = 0 and solve for x. i.e. Ax + B(0) = C. Ax = C. x = C/A. To find the y-intercept, substitute x =0 and solve for y. i.e. A(0) + By = C. By = C. y = C/B. Go through the example given below to understand this concept in a better way. Example: Let us assume the straight-line equation 5x +2y =10
How to calculate y intercept formula?
b is the y-intercept. We can use the following formula to calculate the y-intercept. y – a = m ( x – b ) a and b being a point on a line. Example: Suppose you have a straight line whose gradient is 3 and a point 2,1, calculate its y-intercept. Since the y-intercept is when x=0, therefore; y – 2 = 3 ( x – 1 ) y – 2 = 3x – 1. y = 3x – 1. Therefore, the number that has replaced b is -1, which means that -1 is the y-intercept.
How to find y intercept on a graph or table?
y= – (a/b)x-c/b. keeping -a/b= m and -c/b= c ( new constant) we get the equation as y= mx+c. Note that if x is kept 0 y takes the value equal to c and as mentioned earlier, in order to find the y intercept, the value of x is taken to be 0. Hence, c directly gives the y intercept of the straight line.
