Question

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)

A. m = 4 Point = (1/3, 1)
B. m = 1/3 Point = (1,-4)
C. m = 1/3 Point = (1, 4)
D. m = 1/3 Point = (-1, 4)​

Answer 1

B

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

y + 4 =
`(1)/(3)` (x - 1) ← is in point- slope form

with m =
`(1)/(3)` and (a, b ) = (1, - 4 ) → B
