#### Slide 1 -Quizvraag

5 minutes
Make at least 1 exercise on a paper. Hand in after we discuss the answers.
a) Sketch the graphs of A: y = 2x + 3, B: y = -3x + 5 and C: y = -2x + 3 in one coordinate system.
b) Solve 0.8x - 5.4 = 3.7x + 9.1
c) Solve 2(3x + 2) - 3 = 4x + 8
d) Calculate the coordinates of the point of intersection between the graphs
of y = 2x + 5 and y = 5x - 7
e) Solve 2x + 1 > -6x + 9
f) Rearrange to express a in terms of t: 5t - 3a = 30
g) Substitute formula A in formula B and simplify the result:    A: p = 5t - 4       B: c = 20 - 3p
