Which equation represents a line that passes through (2, - 1/2) and has a slope of 3?
A. y-2 = 3(x + 1/2)
B. y-3 = 2(x + 1/2)
C. y+1/2 = 3(x - 2)
D. y+ 1/2 = 2(x – 3)

Answer 1

y+1/2=3(x-2)

Explanation:

Equation of a straight line is given by;, y-y,=gradient (x-x,) data, y,=-1/2 x=2 and gradient =3. y-(-1/2)=3(x-2). y+1/2=3(x-2) you

Answer 2

C

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 = 3 and (a, b) = (2, -
`(1)/(2)` ) , thus

y - (-
`(1)/(2)` ) = 3(x - 2) , that is

y +
`(1)/(2)` = 3(x - 2) → C
