Lynn starts with $120 in her savings. Each week her brother gives her $16 to do his homework, which Lynn adds to her savings. Create a linear equation that represents Lynn's savings over time.

16x+120=Total savings

Step-by-step explanation:

the 16x represents how much money you earn the x is the number of weeks you did the homework and the plus 120 is the base

69

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
