After exchanging his Canadian dollar to U.S dollar, Greg only has 4/5 of 200 which is equal to 160 U.S dollars. He had spent 3/4 of the U.S dollars he has, which means that he had spent 3/4 of 160 or equal to 120 U.S dollars. He is then left with only 40 U.S. dollars.

1. 4+n
2. n-9
3. 2n + 6
4. n/6
5. 2(n+3)
Step-by-step explanation:
The linear function that goes through the points (2,-4) and (-4,2) is:
y = -x + 2.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
A linear function going through the points (2,-4) and (-4,2) would intersect the parabola at these points, hence these points would be the solution for the system of equations.
The slope of the line is:
m = (-4 - 2)/(2 - (-4)) = -1.
The line goes through point (2,-4), that is, when x = 2, y = -4, which we use to find the y-intercept b.
y = -x + b
-4 = -2 + b
b = -2.
Hence the equation is:
y = -x + 2.
