Question

Which of the following is a correct equation for the line passing through the point (-2,1) and having slope m=1/2

Check all that apply

A. y=1/2x + 2

B.y=-2x + 1/2

C. x-2y= -4

D. y-1= 1/2(x+2)

Answer 1

y = mx + b
1 = -2 (1/2) + b
solve for b ^
1= (-1) + b
2 = b

therefore...
y = 1/2x + 2

Answer 2

Is that only way and the only one?

Answer 3

yes, it would be 'A'
