Final Exam Review - Part 2

What is the formula for calculating the slope of a line?

• 
• 
• 
• 

Convert to the following equation to slope-intercept form:

5x + 3y = 12

• 3y = -5x + 12

• 5x = -3y + 12

• y = -5/3x + 4

• x = -3/5y + 12/5

What is the slope of the line through the points (1, 2) and (8, 6)?

• 7/4
• 4/7
• 5/6
• 6/5

Standard form of a quadratic equation

• y=x²
• y=ax²+bx+c
• y=mx+b
• y=x

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3
• a = 4, b =-8, c =-3
• a = 4, b = 8, c = 3
• a = 4, b = 8, c = -3

What is the range of y = x² - 2x + 6?

• $x\ge5$

• $y\ge5$

• $All\ Real\ Numbers$

• $y\ \le5$

Which expression is equivalent to x² - 4x - 21

• (x + 7)(x + 3)

• (x + 7)(x - 3)

• (x - 7)(x + 3)

• (x - 7)(x - 3)

The value of y varies directly with x. If x = 3 when y = 21. What is the value of x when y = 35?
