Answer:
y = 300
Step-by-step explanation:
The equation of variation in which y varies directly as x is written Mathematically as:
y ∝ x
y = k × x
y = kx
Where k = Proportionality Constant
We find k
a) y = 60 when x = 0.4.
60 = 0.4 × k
k = 60/0.4
k = 150
b) find the value of y when x = 2
y = kx
k = 150
Hence,
y = 150 × 2
y = 300
Answer:
8/10--> 2/10 20 % scnahce of not makin git
Step-by-step explanation:
..........................................
I get the answer being the same y= -1/2x +
Because b in intercept form is "0"
I used
m=y2-y1/x2-x1
M=-3-2/6-4
M=-5/10
M=-1/2
(-4,2)
Y=mx+b
2=-1/2 (-4)+b
B=2-(-1/2)(-4)
B=0
I did the same for second point
And got "0" for b
So my answer is get
Y=-1/2x
Unless someone else gets something else different.
I hope somewhat helps
