Question

write an equation in point-slope form for the line through the given point with the given slope. (10, –9); m = –2 a. y – 9 = –2(x – 10) b. y – 10 = –2(x 9) c. y 9 = –2(x – 10) d. y – 9 = –2(x 10)

Answer 1

Slope m = -2,    Point = (10, -9)

Using:

y - y₁ = m(x - x₁)            x₁ = 10, y₁ = -9

y - -9 = -2(x - 10)

y + 9 = -2(x - 10)

Look through the options for the answer.

Answer 2

Answer:

 x₁ = 10, y₁ = -9

I am 99.9 sure  but let me know if I am wrong
