I really need the answer's pleas help Directions: Use the information given to write the equation of the circle in standard form.

16. center: (-10,-4), point on circle: (4, -2)

17. center: (-9,-3), point on circle: (-11,2) I

18. center: (5,-7), point on circle: (-3,-1)

19. center: (8, 2), point on circle: (14,-1) es​

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

c(x)= 6x + 3
