If the slopes of the 2 lines are equal then they are parallel.
If m1m2 = -1 (where m1 and m2 are the slopes of the 2 lines) then they are perpendicular.
If the 2 slopes do not match either the first or second conditions then they are neither parallel or perpendicular.
3x + 4y = 18......(2,3)
3(2) + 4(3) = 18
6 + 12 = 18
18 = 18...correct
2x - 2y = 2....(2,3)
2(2) - 2(3) = 2
4 - 6 = 2
-2 = 2...incorrect
when (2,3) is subbed into equation 1, it is true
when (2,3) is subbed into the second equation, it is false
the ordered pair (2,3) is not a solution to the system of linear equations
Answer:
y - -x + 2.
Step-by-step explanation:
The line passes through (0, 2) and 5, 1) so it slope = (1-2) / (5-0)
= -1 and the y-intercept is at y = 2 so the equation is
y - -x + 2.
Answer:
0-0=0
(You didn't attach anyting)
Step-by-step explanation:
(10000-4000)/(0-15)
6000/-15
-400
The slope is -400
Choice B
The line goes down. Negative slopes go down.
