Hey I need some help :)

Mathematics
1 answer:
Gre4nikov [31]3 years ago
6 0

Answer:

Net change means the differnce between the before result and the after result. You would subtract the numbers, but if you have a gain(the before result smaller than after result) you would do its absolute value. If it's a loss(the before result bigger than after result) you would put a negative behind its absolute value.

e.g. if 2019 had $1 net worth and 2020 had $2 net worth, since 2>1 it would be |2-1| = 1. If 2019 had $2 net worth and 2020 had $1 net worth, since 1<2 there would be a - |2-1| = -1 net change.

However, if there is no change it would be just 0.

Here's a graph of a linear function. Write the
sweet-ann [11.9K]

Answer:   y = \frac{1}{3}x - 3  

Step-by-step explanation:

We could find two points on graph to find the slope of the graph since we already know its y-intercept.The y-intercept is when x is 0.

We could find the points (0,-3)   and  another points ( 3,-2) to solve for the slope we will find the difference in y and divide it by the difference in the x values.

(0,-3)

(3,-2)    

y     -3 - (-2) = -1

x      0 - 3 =   -3  

-1/-3  =  1/3

so now we know the slope is 1 thirds or 1 over 3 and the y intercept is -3

so the equation will be      y = 1/3x - 3
