Question

1. Choose the point-slope form of the equation below that represents the line that passes through the point (6, −3) and has a slope of 1/2.

A. y-6 = 1/2(x+3)
B. y = 1/2x-6
C. y+3 = 1/2(x-6)
D. x-2y = 12

Answer 1

y=kx+b
k is slope
y=0.5x+b
put point to function (6,-3)
-3=0.5*6+b
b=-6
answer is B

Answer 2

1/2x is \(\frac{1}{2}x\) or \(\frac{1}{2x}\)? probably second because b and c is same then, so question asker should use equation editor or brackets
