Benchmark 2 Review Day 1

Slope from an equation

Remember the slope is in front of the x

y = 5x - 6

Slope is 5

Multiple Choice

What is the slope of the graph y=6x-7?

-7

$-\frac{6}{7}$

$\frac{7}{6}$

Domain from Values

Remember Domain is X-VALUES

Range is y-values

What is the domain?

Remember x values starting and ending!

Multiple Choice

A dolphin jumps out of the water with a starting height of 0 feet. The graph shows the height in feet of the dolphin’s height above the water as a quadratic function of x, the time in seconds the dolphin is in the air before it hits the water again. What is the domain of the function for this situation?

$0\ \le\ x\ \le\ 1.25$

$6\ \le\ y\ \le\ 6.25$

$0\ \le\ y\ \le\ 6.25$

$6\ \le\ x\ \le\ 1.25$

Solving for x

3(2x - 3) = 9
x = 3
x = 1
x = 6

Multiple Choice

Which value of x makes the equation 3.5(2x-4)=21 true?

2.4

-1

Equivalent

2nd Graph

Multiple Choice

Which function is equivalent to g(x) = x² + x – 42?

g(x) = (x-6)(x+7)

g(x) = (x+21)(x-2)

g(x) = (x+6)(x-7)

g(x) = (x-21)(x+2)

Check Points from Equation

Type Equation in y= and 2nd Graph to check points

Multiple Choice

What is the equation in slope-intercept form of the line that passes through the points (8, 10) and (10, 5)?

y = 30x – 2.5

y = 2.5x - 30

y = -30x + 2.5

y = -2.5x + 30
