Aaron has a budget of $100 per month to spend on lunch. He made a table showing the total amount of lunch money he will have lef
Len [333]
(5,100) (10,75)
first find the slope
75-100=-25
10-5=5
-25/5= a slope of -5
the y-intercept is 100 because that is when x is zero
y=-5x+100
then add 5x to each side
5x+y=100 is your final answer.
I find it easier to start in y=mx+b form and go from there. Hope this helped!!

Bethany, Lauren, Amanda, and David all meet at a family reunion. They are comparing their ages. They have found that Lauren is 1
sammy [17]
As stated in the question 
Bethany - x
Amanda - y
the relationships are 
Lauren is 13 years older than Bethany 
Laurens age = x + 13
David is 11 years older than Amanda 
Davids age = y + 11
product of Bethany's and Laurens ages equal to twice Amandas age 
x * (x+13) = 2y
x² + 13x = 2y
divide all by 2
x²/2 + 13/2x = y
if they subtract 20 from Bethany and Laurens, then product is equal to Davids age
(x-20)(x+13-20) = y +11
(x-20)(x-7) = y+11
x² -7x -20x+140 = y+11
x² -27x +129 = y

the 2 equations to determine the relationships are 
y = x²/2 + 13/2x 
y = x² -27x +129
the first option is correct
