The best approximation for the solution of the system of equations is (0.88,0.65).

Given a system of equations is y=-(2/5)x+1 and y=3x-2.

A system of linear equations consists of two or more equations, and one attempts to solve the equations together.

To find the best approximation solution solve the system of equations.

The given system of equations are

y=-(2/5)x+1     .......(1)

y=3x-2           .......(2)

Firstly, substitute the value of y into equation (1) to find the value of x, we get

3x-2=-(2/5)x+1

Now, we will add (2/5)x in both sides, we get

3x-2+(2/5)x=-(2/5)x+1+(2/5)x

3x-2+(2/5)x=1

Further, we will add 2 on both sides, we get

3x-2+(2/5)x+2=1+2

3x+(2/5)x=3

17x/5=3

Furthermore, we will multiply both sides with 5, we get

5×(17x/5)=3×5

17x=15

Now, divide both sides with 17, we get

17x/17=15/17

x=0.88

Further, we will find the value of y by substituting the value of x in equation (2), we get

y=3(0.88)-2

y=2.65-2

y=0.65

Hence, the best approximation for the solution of the system of equations y=-(2/5)x+1 and y=3x-2 is (0.88,0.65).

liubo4ka [24]
Presume y=kx +b,then substitute (3,0)&(5,4),
When x=3,y=0,so 3k+b=0;
When x=5,y=4,so 5k+b=4;
Now u can know that k=2,b=-6.
The answer is:y=2x-6.

11.  y=-1/3x-4

Plug the slope into m in y=mx+b and  then plug in your point and solve for b. You get C

12.  Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9

13.   Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13
