The 2 points closest to the line is (4,12) and (20, 36)
The slope is the change in Y over the change in x:
Slope = (36-12) / (20-4)
Slope = 24 / 16
Slope = 1.5
So now you have y = 1.5x
To find the equation use the formula (y-y1) = m*(x-x1)
y-12 = 1.5(x-4)
Simplify the right side:
y-12 = 1.5x - 6
Add 12 to each side:
y = 1.5x +6
The answer is the 2nd one.

Answer:0.104
Step-by-step explanation:
0.004 is 1/10 times as great as 0.04
Answer:
0.75x+2=0.9
Step-by-step explanation:
To make the fractions into decimals, you divide the numerator by the denominator. So 3/4 would be 3 divide 4, which gets you 0.75. You would do the same with 9/10, dividing 9 and 10, which will get you 0.9. So it'll be 0.75x+2=0.9!

Here we are asked to find the smallest number which must be multiplied to 240 to make it a perfect square .
So , lets do prime factorisation of 240 .
Here , 240 = 2 × 120 .
= 2 × 2 × 60.
= 2 × 2 × 2 × 30.
= 2 × 2 × 2 × 2 × 3 × 5 .
Hence we got 240 = 2⁴ × 3¹ × 5¹ .
Now here we can see that , in order to make a perfect square it should be multiplied by 3 × 5 = 15 in order to make power of prime factors even .
