Can you check these thanks.

Linear Equations
Directions: Write each equation in standard form.

1. y=7x-5
Answer: 7x-y=5

2. y=3/8+5 (3/8 is a fraction)
Answer: 3x-8y=40

3. x= -2/7y+3/4
Answer: x+14y=12

4. 3y-5=0
Answer: x+3y=0

Find the x-intercept and y-intercept of the graph of each equation

5. 2x-y=5
X= 2.5 (2.5,0)
Y= -5 (0,-5)

6. 3x=4y-5
X= 1 2/3 (1 2/3,0)
Y= 1.25 (0/1.25)

7. 3x-6=y
X= 2 (2,0)
Y= -6 (0,-6)

8. 5x+2y=6
X= 1 1/5 (1 1/5,0)
Y= 3 (0,3)

9. y=3x-1
X= 1/3 (1/3,0)
Y = -1 (0,-1)

10. f(x) = -2x+3
F= (0,-3)
X= 1 (1/2,0)

11. 2x+7y=14
X= 7 (7,0)
Y = 2 (0,2)

12. 2/5x+y/4=1
X= 2/5 (2/5,0)
Y = 4 (0,4)
