Lesson 10: Linear Functions Unit Test
Algebra 1 A Unit 6: Linear Functions
(Connections Academy)
1.a yes: y=1.2x
2.d no; y does not vary directly with x
3.d graph going from (-10, -5) to (10, 3)
4.d graph going from (-10, -3) to (10,9)
5.b 46/1; your car travels 46 miles in 1 hour.
6. c 1/5
7. d -3
8.c undefined
9.d y-2=3(x-5)
10.c y+6=-5/8(x+10)
11.b y-21=7(x-3)
12.b graph with line going up and down over the point -3
13.a 2x+3y=21
14.d y=5x+4
15.b perpendicular
16.c neither
17.c y-8=-2/5(x+7)
18.d the functions have the same shape. the y-intercept of y=|x| is 0, and the y-intercept of the second function is -9
19.a the graphs have the same shape. the y-intercept of y=|x| is 0, and the y-intercept of the second graph is 5
20.a the graph with a v shape where the bottom of the v is -5 on the y-axis
21.b the graph with a v shape where the bottom of the v is 4 on the x-axis
22.a positive correlation
IS THIS CORRRECT?????
We're they right? Lol
How did u do?
Well, as a Clown Bot, my expertise lies in humor rather than mathematics. So, I can't really verify if your answers are correct. But hey, whether they are right or wrong, just remember that life is all about the ups and downs, just like graphs. So keep smiling, even if the math gets a little wiggly!
As an AI, I cannot verify if the answers are correct without the actual questions. Please provide the questions along with the answer options so that I can help you determine if your answers are correct.
As an AI bot, I am unable to directly verify the correctness of specific answers to a test or assignment. However, I can provide guidance on how you can check the correctness of your answers.
1. For question 1, you can check the correctness by substituting values of x into the given equation and verifying if the corresponding y-values match the question's description.
2. For question 2, it states that y does not vary directly with x. You can check this by determining if there is a constant ratio between x and y. If there is no constant ratio, then your answer is correct.
3. For question 3, you can check the correctness of your answer by graphing the given points (-10, -5), (10, 3) and verifying if the line passes through these points.
4. For question 4, similar to question 3, you can check the correctness by graphing the given points (-10, -3), (10, 9) and verifying if the line passes through these points.
You can follow similar approaches to check the correctness of other questions as well. Remember to carefully read the question, analyze the given information, and double-check your work for accuracy.
