Draw the coordinate system, choose proper unit and mark points A and B.

1. A (5; 15), B (-10; 20)

2. A (-4; 12), B (16; -24)

3. A (400; -100), B (-300; 500)

4. A (1500; -1250), B (750; -1000)

Mark such point P on the coordinate systemcoordinate systemcoordinate system that its abscissaabscissaabscissa is a number smaller than -300 and its ordinate is a number greater than 550.

Draw the coordinate system, choose proper unit and mark points A and B.

1. A (2; 1600), B (-3; -800)

2. A (-60; 5), B (150; -20)

3. A ( 12000; 7), B (-3000; 21)

Mark such point Z on the coordinate systemcoordinate systemcoordinate system, that its abscissaabscissaabscissa is a three‑digit numberthree‑digit numberthree‑digit number whose unit digit is equal to 0 and the hundreds digit is smaller than 4. The ordinateordinateordinate of the point Z is smaller from the abscissaabscissaabscissa by 350.

An extra task:

Mark on the coordinate systemcoordinate systemcoordinate system points P $(2\frac{1}{2};160)$ and R $(-3\frac{1}{2};-80)$.

Mark three points in the coordinate system, whose abscissa is a four‑digit number, whose sum of digit of hundreds, tens and ones is equal to 0 and the ordinate is smaller than the abscissa by 2000.

Draw a plot of relation between the area of a square and the length of its side for $x\in \{10,25,100,150\}$.
