Raphael graphed the system of equations shown.
y = – 3
y = x – 0.8
what is the best approximation for the solution to this system of equations?

(-2.2,-3)

Step-by-step explanation:

We have been given a system of equations and we are asked to find the best approximation for the solution to this system of equations.

We will use substitution method to solve for the system of equations.

Upon substituting equation (1) in equation (2) we will get,

Upon adding 0.8 to both sides of our equation we will get,

Therefore, the best approximate value of x is -2.2 and approximate value of y is -3.

step-by-step explanation:

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)
