Linear Equations
Directions: Write each equation in standard form.
1. y=7x5
Answer: 7xy=5
2. y=3/8+5 (3/8 is a fraction)
Answer: 3x8y=40
3. x= 2/7y+3/4
Answer: x+14y=12
4. 3y5=0
Answer: x+3y=0
Find the xintercept and yintercept of the graph of each equation
5. 2xy=5
X= 2.5 (2.5,0)
Y= 5 (0,5)
6. 3x=4y5
X= 1 2/3 (1 2/3,0)
Y= 1.25 (0/1.25)
7. 3x6=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=3x1
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)

2 has a wrong sign.3,4 are wrong.
12 x intercept is wrong. 
2x/13x+5/8=0
