Ordered pairs that is satisfy to the equation y=-9x+3

1 answer:

4 0

Let x = 1. Substitute x = 1 into the equation:

y = -9X(1)+3

y = -9+3

y = -6

-> Ordered pairs are written in the form (x,y). Thus in this case, your ordered pair is (1,-6).

What is the solution to this system of linear equations 3x 2y 14 5x y 32

Leya [2.2K]

After simplification, the solution of this system of linear equation is (3.85, 12.75).

In the given question we have to find the solution to this system of linear equations 3x-2y=14 or 5x+y=32.

The given system of linear equations is:

3x-2y=14.......................(1)

5x+y=32.......................(2)

Multiply equation 2 by 2, we get

10x+2y=64.......................(3)

Add equation 3 by 1, we get

10x+2y+3x-2y=64-14

13x=50

Divide by 13 on both side, we get

x=3.85

Now put the value of x in equation 2

5(3.85)+y=32

19.25+y=32

Subtract 19.25 on both side, we get

y=12.75

So, the solution of this system of equation is (3.85, 12.75).

I forgot how to do this lol

astraxan [27]

The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7
=> a= -2
Passes through (4,1) => x=4, y=1
Substituting into the equation:
1= -2x(4) + b => b= 9
=> y= -2x + 9
