Examine the relationship between y and x, waiting until later to examine the y-intercept. For example: If we look at B, and mult. x = 2 by 0.55, we get 1.10, which is not even close to the y = 6.5 given in the table. If, however, we mult. 2 by 3.55, we get 7.10, which is not the same as the y = 6.5 given in the table, but is much closer than 1.10.
Also note that all y values in the table are positive, so a negative slope would be inappropriate. That eliminates choices A and D.
Focus now on the remaining choices B and C. Again, let x= 2 and determine the associated y value. Which y value is closer to the table's 6.5?
B: 0.55(2) + 3.55 = 4.65 (relatively far away from the table's 6.5)
C: 3.55(2) - 0.55 = 6.55 (very close to the table's 6.5)
C is the correct answer.

Step-by-step explanation:
The hanger diagram ideally should be in balance with all the shapes hung on it.
On the left side, it shows that the circles are 9 grams and the squares are 12 grams. The triangles are 2t grams. Therefore, on the left side we have,
9 + 12 + 2t
On the right side, it shows the circles are 6 grams and the squares are 6 grams, while the triangles are 5t grams. Therefore on the right side we have
6 + 6 + 5t.
For the hanger to be in balance, we should have
Answer:
The standard form of this slope-intercept form is x + 4y = 16.
