A line with a negative slope will contain some points in
quadrant II.Click to check answer
ALWAYSHint: lines with negative slopes are falling
from left to right.

30 Always, Sometimes, or Never
The product of the slopes of perpendicular lines is – 1.
Click to check answer
ALWAYSHint: By definition opp. Reciprocals
have a slope of – 1.Click to return to game board
40 Always, Sometimes, or Never
The graph of a line is a function.
Click to check answer
SOMETIMESHint: Vertical lines are the only lines that are not functions
since they have the same x-coordinate used many times.

50 Solve for the Unknown
This is the slope of the x-axis.
Click to check answer
0Hint: The slope of any horizontal line is zero since horizontal lines have a run, but no rise.

40 Everything About Slopes
Find x if is vertical given A(2x + 3, 7x + 1)
and B(5x, x – 9)Click to check answer
x = 1Hint: Denominator of slope must be zero for vertical line.
This is OK since the numerator would then be -16, it cannot also be zero.

This is called the slope-intercept form.
Click to check answer
y = mx + bHint: m is slope and b is the y-intercept

10 Algebra Terms & Symbols
This is the Point-Slope Formula.
Click to check answer
y – y1 = m(x – x1)Hint: Use this formula when you know two points or a point and the slope,
but you do not know the y-intercept.

Jeopardy Directions• Any one student may select the first question and students rotate choosing the next question
in clockwise order regardless of points scored.
• As a question is exposed, EACH student in the group MUST write his solution on paper. (No verbal responses accepted.)
• The first student to finish sets down his pencil and announces 15 seconds for others to finish working.
• After the 15 seconds has elapsed, click to check the answer.– IF the first student to finish has the correct answer, he earns the point value of the question and no
other students earn points.– IF that student has the wrong answer, he subtracts the point value from his score and EACH of the
other students with the correct answer earns/steals the point value of the question. (Those students do NOT lose points if incorrect, only the first student to “ring in” can lose points in this game version.)
• Each student should record a running total of his own score.
• Good sportsmanship and friendly assistance in explaining solutions is expected! Reviewing your math concepts is more important than winning.
