Question

Using point-slope form, write the equation of the line that passes through (2, –1) and has a slope of –5.
A.
(y – 1) = –5(x + 2)
B.
(y – 2) = –5(x – 1)
C.
(y + 1) = –5(x – 2)
D.
(y + 2) = –5(x – 1)

Answer 1

y - y1 = m(x - x1) <== point slope formula
slope(m) = -5
(2,-1)...x1 = 2 and y1 = -1
now we sub
y - (-1) = -5(x - 2)
y + 1 = -5(x - 2) <=== point slope form

Answer 2

I think it's D but I'm not entirely sure. Is it C or D?

Answer 3

its C

Answer 4

ok thank you

Answer 5

no problem :)
