Answer:
the lines are perpendicular
Step-by-step explanation:
You can tell something by looking at the differences of coordinates:
B-A = (6-2, -11-5) = (4, -16) . . . . . Δy/Δx = -16/4 = -4
D-C = (-1-3, 9-10) = (-4, -1) . . . . . Δy/Δx = -1/-4 = 1/4
The product of the slopes of these lines is (-4)(1/4) = -1, so ...
the lines are perpendicular
Answer:
positive the line is going up and it increasing so positive association i've done this b4 trust me
POSITIVE ASSOCIATION
Step-by-step explanation:
Answer:
Choice 2
Step-by-step explanation:
Range is talking about the y value of the coordinates. Choice 2 has all the y value in the function
Answer:
y - 4 = 0
Step-by-step explanation:
They give you the y coordinate, 4, and the x coordinate as 0.
Put 4 in as y.
4 - 4 = 0. That means x = 0 and that is right.
To make sure it has a slope of zero, subtract 4 on both sides.
You get : y = 4. This means that the line will be straight and it will have a slope of zero.
Answer:
x=3
Step-by-step explanation:
The way you find x-intercepts is by setting y equal to 0. So then you just solve for x.
(0)-12=-2(x+3)-2(0)
-12= -2x -6 -0
-12 = -2x -6
-6 = -2x
x = 3
Hope this helped.
