What is the equation of the line in point-slope form that passes through the point (7,-4) and has a slope of 1/2 ?
a. y+ 7 = 1/2 (x – 4)
b.y-7= 1/2 (x + 4)
c.y - 4 = 1/2 (x + 7)
d.y+4 = 1/2(x - 7)

Answer 1

d.
`y+4=(1)/(2)(x-7)`

Explanation:

Here m=1/2 and (x1, y1)=(7, -4)

Equation of line in point slope form is given as

`y-y_1=m(x-x_1)`

Therefore

`y+4=(1)/(2)(x-7)`
