• 6=6 infinite solutions

• 18≠9 no solution

• 9 ≠ 8 no solution

• x= 6 one solution

State the slope and y-intercept:

• m= ⅓

  b= 4

• m= 4

  b= ⅓

• m= -⅓

  b= -4

• reflection

• dilation

State the coordinate of the image of the given point B (4,9) under a dilation with center at the origin with the given scale factor of 2.

• B' (2 , 4.5)

• B' (-8 ,-18)

• B' (8 ,18)

• B' (9 ,4)

What is the solution?

• (1, -1)

• (-1, 1)

• (0, -2)

• (0, 1)

Parallel Lines never intersect because...

• they have the same slopes. 

• they have the same y-intercept.

• they have different slopes.

• they have different y-intercepts. 

Angle 1 = 27^o
Find the measure of angle 4

• 27^o

• 153^o

• 63^o

You need a ladder that will reach up a 25 foot tall house when placed 10 feet away from the house. How tall does the ladder need to be?

• 25 feet

• 26 feet

• 27 feet

• 28 feet

What is the final step in solving this work for c?
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²

• Divide both sides by 2

• Take the square root of both sides

• 4,5,6

• 8,10,12

• 5,12,13

• 5,10,12
