Name the three forms of a line we have studied in this unit.
Slope-intercept
Standard
Point-slope
These kind of lines will never intersect?
Parallel lines, lines with the same slope
Daily Double
You may choose one of the following:
1) All other teams lose 300 points
2) Double your score
Given the slopes are defined, what is the product of the slopes for two perpendicular lines?
"Fractions are friends"
Mr. Muñoz
Daily Double
You may choose:
1) Steal up to 500 points from any team(s)
2) Wager up to 500 points.
When graphing linear equations in slope-intercept form, where do we begin?
In the following linear equation, what is the y-intercept? y = -3/4x
0
Write an equation for a vertical line through the point (-3, 3)
x = -3
"Where's your ID? Take your hood off! Throw away your Dunkin!"
Ms. DiNatale Or The Deans of EHS
Name three ways to describe slope.
Possible answers: rate of change, rise over run, y2- y1/ x2 - x1, Steepness of a line, A ratio, the variable m.
When graphing a line from the point-slope form of an equation, what is the first step?
Find and plot the point (x1,y1) which the line goes through.
y-y1=m(x-x1)
What are the 4 Types of slope?
Negative, Positive, Zero, and Undefined.
Write an equation for a line with the following slope and points.
m = 2/3 and (0, -2), (3, 0)
y = 2/3x - 2
Drake
Find the slope of the line that includes the following points. (4, -5) (-4, 5)
-10/8 which simplifies to -5/4
Describe the graph of the line y = -2
Graph should begin with a point on the y-axis at -2. A horizontal line (Slope=0) should be drawn through -2 extending on both sides of the y-axis.
Write an equation for a line with the following two points. Find the slope and y intercept. (15, -10) (5, 10)
slope = -2 y intercept = 20
y = -2x + 20

The GEICO Gecko
Find the slope of the line that includes the following points. (-12, -9) (-3, -3)
-6/-9 = 6/9 = 2/3
When given the equation of a line in standard form, where do we begin?
Find and then plot the x- and y-intercepts if there are any.
m=2/3 and m=-3/2 are examples of these?
Negative Reciprocal Slopes.
The amount y(in dollars) of money you have left after playing x games at a carnival is y = -0.75x + 10. How much money do you have after playing eight games?
y = -0.75(8) + 10 y = -6 + 10 y = 4 $4 dollars left after playing 8 games. Graph should begin at (0, 10) on the y-axis and move down three and four to the right.
