Question

Which is the point-slope equation of a line with a slope of 1/2 that contains (4,7)

My answer choices are
A= Y - 7 = 1/2 (x+4)
B= Y - 7 = 1/2 (x-4)
C = Y - 7 = - 4 + (1/2)
D = y + 7 = 1/2 (x+

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

Here m =
`(1)/(2)` and (a, b) = (4, 7) , thus

y - 7 =
`(1)/(2)`(x - 4) → B
