Answer:
We have the equation of the line as;
y = 1.80x - 5.80
Step-by-step explanation:
Let us have a plot of the amount saved in dollars to the day number
So we have the amount as y axis values and the day as x axis values
from the question, we can identify the points as;
(6,5) and (11,14)
Mathematically the equation of a straight line can be represented by the equation;
y = mx + b
where m is the slope and b is the y intercept
So, we calculate the slope using the two points above
We have the formula as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (6,5)
(x2,y2) = (11,14)
m = (14-5)/(11-6) = 9/5 = 1.8
So we have the equation as;
y = 1.80x + c
To get the value of c, we use any of the two points
Let us use the point (6,5)
we substitute 6 for x and 5 for y
So, we have ;
5 = 1.8(6) + c
c = 5-1.8(6)
c = -5.8
So we have the equation as;
y = 1.80x - 5.80
