Question

14.

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

(–10, –1); m = -1

A. y + 10 = -(x + 1)

B. y + 1 = -(x + 10)

C. y – 1 = -(x – 10)

D. y – 1 = -(x + 10)

Answer 1

B. y + 1 = -(x + 10)

Explanation:

Use the given slope and point to substitute into the point-slope formula y − y 1 = m ( x − x 1 ) .

Slope-intercept form: y = − x − 11

Point-slope form: y + 1 = − 1 ⋅ ( x + 10 )

Answer 2

B.)y+1= -1(x+10)

Explanation:

y+1= -1(x+10) so the correct choice would be B.
