Example Question #4 : X And 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 : Coordinate Geometry
Give the slope of the line that passes through and .
Use the slope formula, substituting :
Example Question #2 : Coordinate Geometry
What is the slope of the line that passes through and ?
We can use the slope formula:
Example Question #3 : Coordinate Geometry
What is the slope of the line that passes through and ?
We can use the slope formula:
Example Question #2081 : Hspt Mathematics
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 #2083 : Hspt Mathematics
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 #2084 : 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 .
Example Question #2085 : Hspt Mathematics
Begin at the point on the coordinate plane and move four units to the right. Next, move six units up. Where are you now?
Moving four units to the right increases the -coordinate by 4; moving six units up increases the -coordinate by 6. The current location is
, or .
Example Question #2086 : Hspt Mathematics
On the coordinate plane, how do you get from to ?
Move up ten units and right two units
Move right ten units and down two units
Move down ten units and left two units
Move left ten units and up two units
Move right ten units and down two units
The -coordinate changes by units; therefore, you must move ten units in a positive horizontal direction - right.
The -coordinate changes by units; therefore, you must move two units in a negative vertical direction - down.
The correct response is to move right ten units and down two units.
