Question

Write an equation in point-slope form for the line through the given point with the given slope.

(10, –9); m = –2

y – 9 = –2(x – 10)
y + 9 = –2(x – 10)
y – 9 = –2(x + 10)
y – 10 = –2(x + 9)

Answer 1

Hi Patricia;

(10, –9); m = –2

Point-slope formula...

y-y₁=m(x-x₁)

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

Subtracting a negative number is the same as adding a positive number.

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