Honors Algebra I Unit 1 Review

Which of the following is the coefficient in this expression?
50 + 23x - 2

• 63
• 50
• -2
• 23

Which of the following is a constant in this expression?
36v + 27x -57

• -57
• 57
• 27
• 36

What is the definition of a variable?

• It is a number that is by itself
• It is a letter that represents an unknown number
• It is a term
• It is the same as a coefficient

When converting the equation

2x + 4y = 8

into slope-intercept form, the first step to solve for y would be to ____________.

• subtract 2x from each side

• subtract 4y from each side

• add 2x to each side

• add 4y to each side

After subtracting 2x from each side, the resulting equation is shown below:

2x + 4y = 8

4y = -2x + 8

The final step to solve for y would be to ____________.

• divide each term by 4

• divide each term by -4

• add 4 to each side

• subtract 4 from each side

• 2x-6=5x-9

• -6=3x-9

• 3=3x

• 1=x

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

• 10

• 6

• -10

• 6

6x + 10 > 5x - 12

• x > 2
• x < -2
• x < -22
• x > -22

Graph the solution set of the inequality.

–4n + 1 > –23
