2. select the ordered pairs that satisfies the function y= -3x+4
A) (1,-1)
B) (-4,-2)
C) (-1,-1)
D) (2,-2)​

Respuesta :

Step-by-step explanation:

1. y=2x-3 x=1 y=-1

-1=2x1 - 3

-1=2-3

-1=-1 (LHS=RHS) C.(1,-1)

2. y=-3x+4 x=2, y=-2

-2=-3x2 +4

-2=-6 +4

-2=-2 (LHS=RHS) D.(2,-2)

The ordered pair of the linear equations y = 2x - 3 and y = -3x + 4  are as follows:

1. (1, -1)

2. (2, -2)

Linear equation

  • y = mx + b

where

m = slope

b = y-intercept

Therefore,

y = 2x - 3

The value of y is gotten when we substitute the value of x in the equation. Therefore,

y = 2(1) - 3

y = 2 - 3 = -1

Therefore, the ordered pair is (1, -1)

2.

y = -3x + 4

y = -3(2) + 4

y = -6 + 4

y = -2

Therefore, the ordered pair is (2, -2).
