Jeremy surveyed students in his class about their spending habits in the school cafeteria. He used the data to create a scatterplot. How Students Spend Money in the Cafeteria A graph has times buying lunch per week on the x-axis, and dollars spent on the y-axis. A trend line goes through points (2, 5.5) and (5, 15.25). Which is the equation of his trend line?

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
