= kx. where k is the constant of variation. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
Simply so, which graph represents an equation in the form y KX?
Slope of y = kx Theorem The graph of the direct-variation function with equation y = kx has constant slope k. Now solve this system of equations for k. So by the definition of slope, k is the slope of the line through these points. Thus, k is the slope of the line with equation y = kx.
Also, which statement is always true about the graph of an equation in the form y KX Y KX? The equation y = kx is a proportional graph. It means that you multiply x by a number and you have k. The point (0, 0) will always be on the graph, because no matter what K is, if you are multiplying by 0 for x, you will get 0 for y.
Secondly, what is Y KX called?
In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation. In this function, m (or k) is called the constant of proportionality or the constant of variation.
What is direct variation?
Direct Variation. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).

what is the slope?
Answers
Answer:
2/3
Step-by-step explanation:
Find a two coordinates on the line such as (20,40) and (50,60)
plug it into the slope formula m= y2 - y1 / x2- x1
it doesn't matter what way you plug them in
m = slope
m = 60-40 / 50 - 20 = 20/30 = 2/3
The slope is 2/3 I simplified 20/30 by dividing by 10

What is the range of the function f(x) = 3x + 2
when the domain is {-2,-1,2}?
Answers
Answer:
Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)
Step-by-step explanation:
All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

12x > 18x - 27 - 15
12x > 18x - 42
42 > 6x

so, this is true for all values < 7
so, x is in (-infinity, 7)

x=24°
Step-by-step explanation:
(3x-6)°+x°= 90°
4x=90+6
4x= 96°
x= 24°
Answer:
Step-by-step explanation:
(3x-6)°+x°=90°
First, combine like terms:
3x°+x°-6°=90°
4x°-6°=90°
Add 6° to both sides:
4x°=96°
Divide 4 from both sides to isolate x:
x=24°
Check your answer:
3(24)-6+(24)=90°
72-6+24=90°
66+24=90°
90°=90° (correct)
