Andre and Noah started tracking their savings at the same time. Andre started with $15 and deposits $5 per week. Noah started with $3 and deposits $8 per week. The graph of Noah's savings is given and his
equation is y = 8x + 3, where x represents the number of weeks and y represents his savings.
Write the equation for Andre's savings and graph it alongside Noah's. What does the intersection point
mean in this situation?

you just switch the numbers basically so it would be 3/17

b is the correct answer

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
