kim is saving monyfor a trip this summer. She already has some money in her savings account and will add the same amount to her
vlada-n [284]

The linear function represents the amount of money, m, that Carla has saved after w weeks is m = 25 w + 80

Step-by-step explanation:

Carla is saving money for a trip this summer. She already has some money in her savings account and will add the same amount to her account each week

  • At the end of 2 weeks, Carla has $130
  • At the end of 8 weeks, she has $280

Write a linear function in the form y = m x + b to represent the amount of money, m, that Carla has saved after w weeks

The linear equation is y = m x + b, where m is the slope of the line and b is the y-intercept

The formula of the slope is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} , where (x_{1},y_{1}) and (x_{2},y_{2}) are 2 points on the line

∵ The slope is the rate of change of y and x

∴ The same amount of money that Carla add every week = m

∵ At the end of 2 weeks, Carla has $130

∴ The first point is (2 , 130)

∵ At the end of 8 weeks, she has $280

∴ The second point is (8 , 280)

∵ m=\frac{280-130}{8-2}=\frac{150}{6}=25

∴ The same amount of money that Carla add every week = $25

∵ The amount of money that Carla saved after w week is m

∴ m = 25 w + b, where b is the initial amount of money that she

   saved in her account

To find b substitute w and m by the coordinates of one of the two

given points, let us use the first point

∵ w = 2 and m = 130

∵ m = 25 w + b

∴ 130 = 25(2) + b

∴ 130 = 50 + b

- Subtract 50 from both sides

∴ 80 = b

∴ m = 25 w + 80

The linear function represents the amount of money, m, that Carla has saved after w weeks is m = 25 w + 80

Which of the following equations is direct variation? Y=2x,y=x+2,y=2,y=-2x-1
Andrew [12]

Answer:

y=2x

Step-by-step explanation:

Direct variation is such that y=kx where k is the rate of change.  In direct variation the graph must cross the origin (0,0) meaning that the y-intercept is zero.  The only equation that satisfies the definition of direct variation is y=2x.
