| Question | Answer |
| Solve 2(-8 - 3x) + 5 = -53 | x = 7 |
| How many solutions does the equation -9x + 10 = 12 - 9x have? | None |
| Solve | |
| Draw a reflection of the figure in the y-axis. | |
| Rotate the figure 90° counterclockwise about the origin. | |
| Translate the figure 5 units right and 3 units up. | |
| A square is reflected, rotated, and translated. Is the new image congruent to the original? | Yes - reflected, rotated, and translated images are always CONGRUENT. Congruent means that all corresponding side lengths and angles are EQUAL. |
| Identify the corresponding parts. | |
| In the figure,∆ABC is congruent to ∆XYZ. Write a sequence of transformations in which ∆XYZ is the image of ∆ABC. | Reflection over the y-axis and then translate 8 down and 5 right OR Translate 8 up and 5 left and then reflect over the y-axis. |
| Are the two figures similar? | No - side ratios are not equal. |
| In the figure, ∆ABC is similar to ∆DEF. Write a sequence of transformations in which ∆DEF is the image of ∆ABC. | A dilation with respect to the origin using a scale factor of 2 followed by a reflection in the y-axis OR A reflection in the y-axis followed by a dilation with respect to the origin using a scale factor of 2. |
| Find the value of x. | x = 125° |
| Find the measures of ∠1 and ∠2. | |
| Tell whether the triangles are similar. | YES - all 3 angles are equal. |
| The vertices of a triangle are A(-4, -1), B(0, 5), and C(4, -4). Draw its image after a dilation with respect to the origin using a scale factor of 2. | |
| Plot the solution of the system. y = x + 5 y = 3x - 5 | (5, 10) |
| Find the slope of the line. | 1/3 |
| Write in slope-intercept form an equation of the line that passes through the points (-1, 3) and (1, -11). | y = -7x - 4 |
|
Write an equation of the line in slope-intercept form.

| Graph | |
| The profit y (in dollars) for a company for selling x shirts is represented by y = 12x. Graph the equation. Is this relationship a direct variation? | Yes, this is a Direct Variation - Linear with (0, 0) |
| The graph shows the number of helmets purchased and the total cost. What is the cost per helmet? | $13 per helmet |
| The distance Bus A travels is y = 75x. The graph shows the distance Bus B travels. Which bus is traveling faster? | Bus A |
| The total cost at Arcade A is y = 0.50x + 4. The table shows the total cost at Arcade B. Which has the higher entrance fee? Which has the higher fee per game? | Arcade B has the higher entrance fee. Arcade B also has the higher fee per game. |
| Which table is linear? | Table A |
| Which graph is linear? | Both Graphs are linear. |
| The equation y = 30x + 200 represents the total money y (in dollars) that Kate has in her savings account after x months of saving. What is the slope? What does the slope mean? What is the y-intercept? What does the y-intercept represent? | Slope is 30. This means Kate is saving $30 each month. The y-intercept is 200. This represents the amount of money Kate had when she started saving. |
| Which graph represents a constant increase? Which graph represents a constant decrease? | Graph B shows a constant increase. Graph A shows a constant decrease. |
