Algebra 1 1st semester review

Evaluate when x = -5 and y =3
7y - x 

• 16
• 26
• 6
• 36

Solve.
84 = 75 - x

• x = 1
• x = 11
• x = -9
• x = 9

Solve.
3(2x - 8) = -24 + 6 x

• No Solution
• x = 1
• Infinitely Many Solutions
• x = -2.5

Simplify
10x - 4(2x - 9)

• 18x + 36
• x = 18
• 2x + 36
• 12x + 36

Find the slope of a line that passes through the points (3, -4) and (1, 0)

• m = 1/2
• m = -1/2
• m = 2
• m = -2

Which point is not a solution to the inequality?
   
     4x - 3y > 18

• (1, -6)
• (10, 6)
• (5, -1)
• (3, -2)

Which kind of line is y = 7?

• Horizontal
• Vertical

Choose the line that is parallel to the line
 y = 3x - 4

• y = x - 4
• y = -3x + 4
• y = 3x + 1
• y = x + 3

Choose the line that is perpendicular to the line
y = 1/2x + 4

• y = -2x - 1
• y = 2x
• y = 1/2x -5
• y = x + 4

Solve for y.
3y - 2x = -6

• y = 2/3x - 6
• y = 2/3x - 2
• y = 2x - 2
• y = 2x + 6
