§3.2 Relationships
  1. Express relationship not in words , but a formula
  2. Three times as large as...., six smaller than..., three times larger..., squared, 10 minus the x-coordinate, equal to 1 and independant of,.......
  3. Replace 'x' for a number to get 'y' for coordinates
  4. Table of values 
  5. Calculate the y-coordinate, set up a formula, read off coordinates, draw a graph

Slide 6 - Tekstslide

Ga de punten langs. Een krul wanneer ze het beheersen. Tel aantal krullen. Aantal krullen staat gelijk aan emoji. Dus 4 krullen, dan 4e emoji van links
How confident are you about §3.2?

§3.3 Formulas and graphs
  1. Multiplication sign as a 'dot' or left out completely
  2. Order of operations when calculating a y-coordinate
  3. 1 and -1? Leave the 1 out when in front of a variable (letter)
  4. Draw a graph by making a table of values,
    draw a coordinate system with a suitable scale,
    plot the points and connect them. 
  5. Calculate the y-coordinate, set up a formula, read off coordinates, draw a graph

Slide 11 - Quizvraag

§3.4 Linear and quadratic relations
  1. Linear relationship --> graph is a line (constant rate), 
    number in front of 'x' is the amount of change per step
  2. Quadratic relationship --> square, parabola (upward/downward),
    vertex
  3. Brackets are possible in a formula 
y=2x2+4
y=2x+4
Positive number in front of x^2
Negative number in front of x^2
y=2x2+4

Slide 12 - Tekstslide

Vraag de leerling welke formule lineair is
§3.5 Variables
  1. Other relationships than the x- and y-coordinates
  2. Variables--> Independent (x) and dependent (y)
  3. Tables and graphs --> familiar?

y=2x2+4
Linear graph is a line. You need three points to draw this line
Quadratic graph (parabola) is a curve and you need at least seven points with the vertex in the middle
y=2x+4
x

independent
horizontal

Friday - last lesson...
  • HW : See notebook.
    Write down what you have already done for maths per day. Make a picture of it, because you will upload that during the lesson
  • Preparing for the test by doing exercises? I would advice the following: Do ex. 62, 63, 64, 68, 69 and 70 on p. 83 
20-12
24-12
28-12
2-1
