Which linear equation represents a proportion relationship?

A) y = x + 2

B) y = 3x + 0.2

C) y = -0.3x

D) y = 3x + 4

Answers

Answer:

C

Step-by-step explanation:

C because in proportions your multiply and divide, not add or subtract. Example: 2/3=4/5 is 2x5 and 3x4 which equals to 10=12 therefore 2/3=4/5 is not proportional. If they equaled they would be proportional.

For the translation, I believe it would be:
First; a reflection over the Y axis and the new points would be A(4,4) B(2,2) C(2,-1) D(4,1). (The Y value should be the same and the X axis should be the opposite)
Second; It should be moved three units down to get the points that A’ B’ C’ and D’ lie

I *think* they are congruent. I forgot what it exactly means, but they still have the same shape size and have all the same angles.

Answer:

21. The slope is 50.

22. 0

23. y=50x

24. $2600

Step-by-step explanation:

21. The slope of the line is 50. Slope is defined as "rise over run". As the line increases, each segment moves up the y-axis by $50, and to the right on the x-axis 1 segment. (Work: 50 divided by 1)

22. The y-intercept is (0, 0), or simply 0. If you look at the graph you can see that the line crosses the y-axis at the origin. This makes the y-intercept equal to 0.

23. The slope tells you that the student makes $50 every week. The y-intercept is 0. Using the formula y=mx+b, an appropriate equation would be y=50x.

24. The equation found in problem 23 can me used to determine how much a student makes (y) after "x" weeks. Substitute 52 for x to solve for y. This becomes y=50(52). This can be simplified to y=2600. This means that after 52 weeks, the student will have made $2,600.

slope is 50
