Step-by-step explanation:

Vẽ đồ thị y = 2x (1):

Cho x= 0 ⇒ y= 0 ta được O (0, 0)

Cho x= 2 ⇒ y = 4 ta được điểm (2; 4)

- Vẽ đồ thị y = 0,5x (2):

Cho x= 0 ⇒ y = 0 ta được O (0; 0)

Cho x = 4 ⇒ y = 2 ta được điểm (4; 2)

- Vẽ đồ thị y = -x + 6 (3):

Cho x = 0 ⇒ y = 6 được điểm (0; 6)

Cho y = 0 ⇒ x = 6 được điểm (6; 0)

Y = mx+b is slope intercept form

m is your slope, the number that m is tells you how many times you go up and over (rise over run)

b is your y intercept, this number tells you where your line should pass

a. y = 2x +1
plot a point at 1 for y, then go up 2 over 1 and draw a line

2 also means 2/1 so you go up twice and over once

b. y = -3x -2
plot a point at -2 for y, and then go up 3 and over 1 but since it’s a -3 you go down 3 over 1

the - shows that your line should be facing the left because it’s a negative slope

c. and d. are hard to see so i can’t tell if that is a = sign or a - sign

but if it’s a = sign follow the steps like the other problems if it’s a - sign solve for y so it turns into slope intercept form then follow the steps like the other problems
