Question

Select the correct answer. Which equation is a point-slope form of the equation of this line? A. `-2x + y + 5 = 0` B. `y = 2x ? 5` C. `(y + 1) = -(1)/(2) (x ? 2)` D. `(y? 1) = 2(x+ 2)`

Answer 1

Answer:

C) and D)

Step-by-step explanation:

A point slope equation is given by:

$y-y_{0}=m(x-x_{0})$ (1)

• m is the slope of the line
• y(0) and x(0) are constant values

Therefore:

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

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

Both of them agree with the equation (1).

I hope it helps you!
