Example Question #1 : How To Find X Or Y Intercept
Give the -intercept, if there is one, of the graph of the equation
The graph has no -intercept.
The graph has no -intercept.
The -intercept is the point at which the graph crosses the
-axis; at this point, the
-coordinate is 0, so substitute
for
in the equation:
However, since this expression has 0 in a denominator, it is of undefined value. This means that there is no value of paired with
-coordinate 0, and, subsequently, the graph of the equation has no
-intercept.
Example Question #2 : How To Find X Or Y Intercept
Give the -intercept, if there is one, of the graph of the equation
The graph has no -intercept.
The -intercept is the point at which the graph crosses the
-axis; at this point, the
-coordinate is 0, so substitute
for
in the equation:
The -intercept is
.
Example Question #3 : How To Find X Or Y Intercept
Give the -intercept, if there is one, of the graph of the equation
.
The graph does not have a -intercept.
The -intercept is the point at which the graph crosses the
-axis; at this point, the
-coordinate is 0, so substitute
for
in the equation:
The -intercept is the point
.
Example Question #1 : How To Find A Line On A Coordinate Plane
Give the slope of the line that passes through and
.
Use the slope formula, substituting :
Example Question #2081 : Hspt Mathematics
What is the slope of the line that passes through and
?
We can use the slope formula:
Example Question #301 : Geometry
What is the slope of the line that passes through and
?
We can use the slope formula:
Example Question #302 : Geometry
What is the slope given the points and
?
Write the slope equation, substitute the point values, and solve for the slope.
Example Question #2082 : Hspt Mathematics
A point is shifted
to the left and
down. What is the new point?
A point is defined as . If the point is shifted left or right, the
value will be added or subtracted. If the point is shifted up or down, then the
value will be added or subtracted.
3 units to the left is:
5 units down is:
The new point is:
Example Question #302 : Geometry
Shift up
and left
. State the new point.
The movement of a point left and right will change the x-value of the point, as movement up and down will change the y-value of the point.
Three units up is adding three to the y-value.
Left three units is subtracting three from the x-value.
The point is:
Example Question #2083 : Hspt Mathematics
Begin at the point on the coordinate plane and move six units to the left. Where are you now?
Moving six units to the left changes the -coordinate of the point by subtracting six from it, while preserving the
-coordinate. The ordered pair of the new location is
, or
.
