Direct Variation. Since k<span> is constant (the same for every point), we can find </span>k<span> when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x , and y = 6 when x = 2 , the constant of variation is </span>k<span> = = 3 . Thus, the equation describing this direct variation is y = 3x .</span>
Follow along with these steps, if you need an explanation, please let me know. :3
Answer:
15: A
16: C
Step-by-step explanation:
I have no idea but hopefully I helped you
Answer:
D
Step-by-step explanation:
We can tell that the final number must be -2 from the graph. This means we can cross off A and C. We can also tell that 2/3 must be negative since the graph curves downwards.
Below is the graph for this equation.
