Need help help with this algebra 2 question.

Question

Part 1: Find the slope of the line that passes through the points (2, 1) and (2, 0).

Part 2: In two or more complete sentences, explain why it is not possible to write the equation of the given line in the traditional version of the slope-intercept form of a line.

Part 3: Write the equation of the line that passes through the points (2, 1) and (2, 0).

Answer 1

slope=rise/run

slope=(1-0)/(2-2)=1/0

there is no slope because of the 0 in the denominator

 

y=mx+b is the slope-intercept form but there is no slope and no y-intercept

the equation of the line is x=2, which is a vertical line parallel to the y-axis

y can be any number and x will always be 2 (2,y)
