Question

Which is the equation of a line that passes through the point (3, -4) and has a slope of 2.

Answer 1

\[y-y_{0} = m(x-x_{0})\]

Where y0 is a y coordinate on the line, x0 is an x coordinate on the line, and m is the slope.
You can just plug in the values you were given to find your answer.

Answer 2

Huh..?

Answer 3

you were given the ordered pair (3, -4) that defines a point with x-coordinate 3 and y-coordinate 4.
Which means
\[y_{0}=4\]
\[x_{0} = -3\]
\[m=2\]
Try substituting these values into the equation I gave you :)

Answer 4

Sorry, y0 = -4 and x0 = 3
