What is the point on a cordinate grid where a line intersects the y axis?
It is the y intercept.
When the graph of a quadriatic function crosses the x axis twice the x cordinate of the vertex lies where between the two intercepts?
Precisely midway. That is to say, at their mean (average).
What is the vertex of y equals x plus 1?
y = x +1 is the equation of a straight line and so has no vertex.
How do you find the x intercepts using the vertex and y intercept?
It depends on the vertex of what!
Where is the vertex of a parabola?
when the function is in vertex form: y = a(x - h)2 + k, the point (h, k) is the vertex.
What is the point on a cordinate grid where a line intersects the y axis?
It is the y intercept.
Is the x cordinate of a point on the y axis zero?
yes, any point " on the y-axis" has its x co-ordinate as zero.
When the graph of a quadriatic function crosses the x axis twice the x cordinate of the vertex lies where between the two intercepts?
Precisely midway. That is to say, at their mean (average).
What is the vertex of the equation y equals 2x-1?

What is the vertex of y equals x plus 1?
y = x +1 is the equation of a straight line and so has no vertex.
How do you find the x intercepts using the vertex and y intercept?
It depends on the vertex of what!
Which is the vertex for y equals 2x - 7?
-5
To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the of the vertex?
To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the right of the vertex.
Where is the vertex of a parabola?
when the function is in vertex form: y = a(x - h)2 + k, the point (h, k) is the vertex.
How do you write y equals x minus 4 x plus 2 in vertex form and find the vertex?
The given equation is y = x - 4x + 2 which can be written as y = -3x + 2 This is an equation of a straight line. Therefore it has no vertex and so cannot be written in vertex form.
When a parabola opens upward the y coordinate of the vertex is a what?
Opening up, the vertex is a minimum.
Vertex for y equals x2 plus 2x plus 1?
The vertex is at (-1,0).
