Which equation represents a line that passes through (2, -1) 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)

Given:

The slope of the line is 3.

The line passes through the point (2,-1).

To find:

The equation of the line.

Solution:

Point slope form of a line: If a line passes through the point with slope m, then the equation of the line is

The line passes through the point (2,-1) with slope 3. So, the equation of the line is

Therefore, the required equation is . Hence, all the options are incorrect.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
