Can you make sure my Algebra II work is correct? I've done the problems. I just want to make sure I am right.
1. Write an equation of the line with a slope of 5 and a yintercept of 3.
y=5x3
2. Write the equation of a line that passes through (9, 3) and has a slope of 2/3
y3=2/3(x9)
y3=2/3x+6
+3 +3
y=2/3x+9
3. Write the equation of a line the line that passes through (3, 9) and is parallel to the line y = 5x  15.
y9=5(x3)
y9=5x15
+9 +9
y=5x6
4. Write an equation of the line that passes through (1, 1) and is perpendicular to the line y=1/2+6.
y+1=2(x1)
y+1=2x2
1 1
y=2x3
5. Write an equation of a line that passes through (8, 5) and (11, 14)
145 /118= 9/2
y5=9/2(x8)
y5=9/2x36
+5 +5
y=9/2x31

The first 4 are correct
In #5 you got 118 = 2 , should have been 3
I trust you can correct it accordingly, you appear to know what you are doing.
