Activity 2. Find at least 2 ordered pairs that satisfy the following equation.
y = 3x + 9
y=-2x - 7
x + y = 10
x2 + y = 2

Answer:

1. y= 3x+9

let x be equal to 0

y= 3(0)+9

y= 9

let y be equal to 0

0=3x+9

use the addition property if equality and u'll get this;

-3x=9

solve for x;

x= -3

ordered pairs that will satisfy to the expression:

(-3,0) & (0, 9)

2. y= 2x-7

let x=0

y= 2(0)-7

y= -7

let y=0

0= 2x-7

use the addition property if equality and u'll get this;

-2x=-7

lastly, solve for x;

x= 7/2

ordered pairs that will satisfy to the expression:

(7/2,0) & (0,-7)

3. x+y= 10

let y=0

0+y= 10

y= 10

let y=0

x+0= 10

x= 10

ordered pairs that will satisfy to the expression:

(10,0) & (0,10)

4. 2x+y =2

note: a number is written first before the variable. (not x2, number should come first)

let x=0

2(0)+y= 2

2+y= 2

y= 2-2

y= 0

let y=0

2x+0= 2

2x= 2

x= 1

ordered pairs that will satisfy to the expression:

(1,0) & (0,0)
