Homework Help: Algebra II

Posted by Andrea on Thursday, October 4, 2012 at 12:50pm.

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 y-intercept of -3.
y=5x-3

2. Write the equation of a line that passes through (9, 3) and has a slope of 2/3
y-3=-2/3(x-9)
y-3=-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.
y-9=5(x-3)
y-9=5x-15
+9 +9
y=5x-6

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(x-1)
y+1=2x-2
-1 -1
y=2x-3

5. Write an equation of a line that passes through (8, 5) and (11, 14)
14-5 /11-8= 9/2
y-5=9/2(x-8)
y-5=9/2x-36
+5 +5
y=9/2x-31
