Choose a system of equations with the same solution as the following system:

6x + 2y = −6
3x − 4y = −18

8x + 4y = −4
17x + 2y = −28
12x + 4y = 12
21x + 2y = −36
6x + 8y = −36
15x + 6y = −60
6x + y = 15
15x − y = −9

table 3 represents a direct variation function. : )

the answer to question 1 is -8, 28.

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
