Multiple Choice

Examine the figure below. Which represents the front view of the 3-D figure?

Multiple Choice

Three different views of a three-dimensional figure constructed from cubes are shown. Which of the following figures could these views represent?

Multiple Choice

Solve the equation:

$$4x-5x+9=5x-9$$  

• x = -3
• x = 9
• x = 3
• x = -9

​When solving equations using Desmos:

​4x - 5x + 9 = 5x - 9​​

​Line 1

​Line 2

Multiple Choice

Solve for x: $$4(1-x)+3x=-2(x+1)$$  

• x = -6
• x = 6
• x = 3

Multiple Choice

Identify the slope and y intercept in the equation of the line:

$$y=-\frac{1}{3}x+1$$  

• Slope: $$\frac{1}{3}$$   y-intercept: $$1$$  

• Slope: $$\frac{1}{3}$$   y-intercept: $$-1$$  

• Slope: $$-\frac{1}{3}$$   y-intercept: $$1$$  

• Slope: $$-\frac{1}{3}$$   y-intercept: $$0$$  

​y-intercept

Multiple Choice

• 2

• -1

• 8

• -4
