Example Question #21 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points is on the line 
Start by rewriting the equation into slope-intercept form.
To find which point is on the line, take the 
Plugging in 
Thus, 
Example Question #22 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points is on the line 
Start by rewriting the equation into slope-intercept form.
To find which point is on the line, take the 
Plugging in 
Thus, 
Example Question #23 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points is found on the line 
Start by rewriting the equation into slope-intercept form.
To find which point is on the line, take the 
Plugging in 
Thus, 
Example Question #21 : How To Find Out If A Point Is On A Line With An Equation
True or false:
The line of the equation 
True
False
False
A line of an equation passes through the point with coordinates 
The line does not pass through the point.
Example Question #22 : Other Lines
True or false:
The line of the equation 
False
True
True
The coordinates of the origin are 
The statement is true, so the line does pass through the origin.
Example Question #26 : How To Find Out If A Point Is On A Line With An Equation
True or false:
The lines of the equations
and
intersect at the point 
(Note: You are given that the lines are distinct)
False
True
False
If two distinct lines intersect at the point 
Examine the second equation:
False; 
Therefore, the lines cannot intersect at
