Start off by writing the equation y = mx - b. Then plug in what you do know
3 = 2(-1) - b (m is the slope and parallel lines have the same slope). Then solve
3 = -2 - b
<u>+2 +2</u>
5 = b
So y = 2x + 5
Each of A, C, and D are rational, so presumably B is the answer here.
A is rational, since
, so
.
C is also rational. If
, then
. This would mean
, and so
.
D is rational by a similar argument. If
, then
. So,
, which means
.
Answer:
y = -3x -16
Step-by-step explanation:
For problems like this, I like to start with a variation of the point-slope form of the equation of a line:
y = m(x -h) +k . . . . . for a line with slope m through point (h, k)
For your given values, this is ...
y = -3(x +3) -7
y = -3x -9 -7 . . . . eliminate parentheses; next, combine terms
y = -3x -16
Hope this helps! ;)
