Answer:
The equation of the line will be:

Step-by-step explanation:
Given the points
Finding the slope between (3, 4) and (12, 9)




The equation of the line can be obtained using the point-slope form of the equation of the line

substituting the values m = 5/9 and the point (3, 4)



Therefore, the equation of the line will be:

Answer:
D. Energy.
Step-by-step explanation:
Liquid is at a higher energy state than a solid.
To solve this problem, you should find the rate ---> cost per yogurt (cost/yogurt)
$6.50/10 yogurts = $0.65/yogurt
It costs $0.65 per yogurt, so you can multiply 9 by $0.65 to find the total cost of 9 yogurt.
9(0.65) = $5.85
