Example Questions
Example Question #41 : Coordinate Geometry
What is the slope of a line running through points 
The slope is equal to the difference between the y-coordinates divided by the difference between the x-coordinates.
Use the give points in this formula to calculate the slope.
Example Question #42 : Coordinate Geometry
Find the slope of the line that goes through the points
Use the following formula to find the slope:
Plug in the given points to find the slope.
Example Question #43 : Coordinate Geometry
Which of the following points is on both the line
and the line
In the multiple choice format, you can just plug in these points to see which satisfies both equations. 
Alternatively (or if you were in a non-multiple choice scenario), you could set the equations equal to each other and solve for one of the variables. So, for instance,
and
so
Now you can solve and get 
Example Question #1 : How To Find Out If A Point Is On A Line With An Equation
A line has the equation 
Plug the x-coordinate of an answer choice into the equation to see if the y-coordinate matches with what comes out of the equation.
For 
Example Question #1 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points lies on the line with equation 
To find which point lies on the line, plug in the x-coordinate value of an answer choice into the equation. If the y-coordinate value that comes out of the equation matches that of the answer choice, then the point is on the line.
For 
So then, 
Example Question #2 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points lies on the line with the equation 
To find if a point is on the line, plug in the x-coordinate of the answer choice into the given equation. If the resulting value for the y-coordinate matches that of the answer choice, then that point is on the line.
For 
Example Question #3 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points lies on the line with the equation 
To find if a point is on the line, plug in the x-coordinate of the answer choice into the given equation. If the resulting value for the y-coordinate matches that of the answer choice, then that point is on the line.
For 
Example Question #4 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points lies on the line with the equation 
To find if a point is on the line, plug in the x-coordinate of the answer choice into the given equation. If the resulting value for the y-coordinate matches that of the answer choice, then that point is on the line.
For 
Example Question #5 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points lies on the line with the equation 
To find if a point is on the line, plug in the x-coordinate of the answer choice into the given equation. If the resulting value for the y-coordinate matches that of the answer choice, then that point is on the line.
For 
Example Question #6 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points is on the line with the equation 
To find if a point is on the line, plug in the x-coordinate of the answer choice into the given equation. If the resulting value for the y-coordinate matches that of the answer choice, then that point is on the line.
