To get X and Y by itself, move everything else to the other side of the equal sign. Do this by doing the opposite operation.

Example: x-2y=11
add 2y to both sides to get x by itself
x=2y+11

Which of the following is a correct equation for the line passing through the point (-1,4) and having slope m=-3

timurjin [86]

Answer:

y = -3x + 1

Step-by-step explanation:

Starting with the point (-1, 4) and the slope m = -3, write out the point-slope equation of a straight line: y - k = m(x - h) becomes y - 4 = -3(x + 1), or:

y = -3x - 3 + 4

y = -3x + 1 This is the same as answer choice (b).
