Is the x coordinate of a point on the y axis always zero never zero or sometimes zero?
The y-axis has the equation x=0, so every point on the y-axis has an x coordinate of zero.
Which ordered pair represents the y-intercept of the graph of the equation y -3x - 9?
-12
How do you identify the ordered pair of an x intercept?
The x-intercept is where x is equal to zero, so look for a pair where x is zero, such as [0,7].
What does the y intercept have to do with the graph?
The y-intercept on the graph shows where the graph crosses the y-axis. The value is always the value of y at that point, because x is always equal to zero.
How do you find the x and y intercepts of an equation?
Substitute zero for x to find the y-intercept, and substitute zero for y to find the x-intercept.
Is the line that crosses the y-axis called a y-intercept or a x-intercept?
A line is just a line, but the y-coordinate (the point where the line intersects the y-axis) is termed the y intercept. This point has an x coordinate that is always zero and the y coordinate can be positive, zero, or negative
What does every y - intercept have in common?
Its x coordinate is 0.The abscissa (x-coordinate) is zero.
Where is the x-intercept located?
The x intercept is the point where the graph intersects the x axis. The young coordinate of this point is zero.
What are the coordinates of the y-intercept of a line?
The x-coordinate is zero. The y-coordinate depends on the individual line.
When a point lies on the x - axis what do you know about its y- coordinate?
When a point lies on the y-axis, its x coordinate must be zero.
What are the coordinates of the y-intercept in the graph of the equation x plus y equals negative 9?
The y intercept will be where the x-coordinate is zero, so set x=0 in the equation and you have: 0 + y = -9, or y = -9. Coordinate (0,-9)
Does a graph of a linear equation always have an x intercept?
No; if the slope is zero and it is above or below y=0 it will not have an x intercept.
What is the x intercept for the equation y equals -2x-4?
2
What is y-intercept y - 2x equals 7?
The y-intercept will occur where the x coordinate equals zero. Substituting x=0 into the equation, we have y - 0 = 7 --> y = 7, so the y-intercept is 7.
Is the x coordinate of a point on the y axis always zero never zero or sometimes zero?
The y-axis has the equation x=0, so every point on the y-axis has an x coordinate of zero.
What is intercept form in algebra?
Intercept for a straight line graph. y = mx + b, where y is the y coordinate, m is the slope, x is the x coordinate, and b is the y-intercept.
Which ordered pair represents the y-intercept of the graph of the equation y -3x - 9?
-12
