Thay `a=2` vào `y=ax+2`. Ta có:

`y=2x+2`

*Vẽ đths `y=2x+2`

Cho `x=0 ⇒ y=2 ⇒` Điểm `A(0;2) ∈ y=2x+2`

Cho `y=0 ⇒ x=-1 ⇒` Điểm `B(-1;0) ∈ y=2x+2`

Vậy 2 điểm `A(0;2)` và `B(-1;0)` là đths `y=2x+2`

Khi a=2 thì y=2x+2

$\text{ +) Khi x=0; => y=2.0+2 = 2; }$

$\text{ => Ta có điểm (0;2) thuộc đồ thị}$

$\text{ +) Khi y = 0; => 0=2x+2; <=> x = -1}$

$\text{ => Ta có điểm (-1;0) thuộc đồ thị}$

$\text{ Vậy => đồ thị là đường thẳng đi qua 2 điểm (0;2) và (-1;0)}$
