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 – 9 = -2(x - 10)
c. y – 10 = -2(x + 9)
d. y – 9 = -2(x + 10)

Answer 1

point slope form is
y - yo = m ( x - xo)
plug in
y-(-9) = -2 ( x-10)
y+9 = -2(x-10)

That is A
