Zad. 1
Funkcja liniowa f(x) = y = ax + b
a)
[tex]y = 2x + 5 \\\\ a = 2 \ i \ b = 5[/tex]
b)
[tex]y = - \frac{1}{2} x - 3 \\\\ a =- \frac{1}{2} \ i \ b = - 3[/tex]
c)
[tex]y =\sqrt{3}x \\\\ a =\sqrt{3} \ i \ b = 0[/tex]
d)
[tex]y =\frac{4 - 2x}{2} = \frac{\not{2}^1 \cdot (2-x)}{\not{2}_1}= 2-x = - x+2 \\\\ a =-1\ i \ b = 2[/tex]
