CF = FG = GC because it is equilateral triangle
So
3x + 0.8 = 2x + 3
3x–2x = 3 – 0.8
X = 2.2
Putting this value to DE
IT IS ALSO A EQUILATERAL TRIANGLE
SO
5x + 4 = 5× 2.2 +4 =
11+4 = 15
All side will be 15 of triangle CD = DC = CE = 15

The required system of linear equations is y = -4x + 1 and y = 5x - 8.
Given that,
From the graph,
system of linear equation is to be determined.
Here,
The slope-intercept form of linear equation.
y = mx + c - - - - - (1)
Equation of line 1
Since point (-1, 5), (0, 1) lies on the line 1.
The slope of line 1,
m = 1-5 / 0+1
m = -4
Now put this slope and 1 point in the equation.
5 = -4(-1) + c
c = 5 - 4
c = 1
now, put m and c in equation 1
y = - 4x + 1
Similarly, the equation of line 2 is given as y = 5x - 8.
Thus, the required system of linear equations is y = -4x + 1 and y = 5x - 8.

Y=kx, k is not equal to 0
when y=6, x=72, 6=72k
k=1/12
so y=1/12*x
when x=8, y=1/12*8=2/3
