In the slope intercept form, b represents the y intercept.
y = mx +- b
Therefore, if the y intercept is at 6, the formula of the line will look like
<span>y=mx + 6
</span>
This eliminates the first two options,
and
and leaves behind
and
Since the line you indicated is sloping downwards towards the lower right hand corner. It must have a negative slope.
Therefore, the answer must be the 3rd option.

By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.
Given that,
(2.310⁵)(1.5
10⁴)
By using scientific notation
The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.
Now, we calculate
(2.310⁵)=2.5
100000=230000
(1.5 10⁴)=1.5
10000=15000
Now,
=23000015000
=3450000000
=345 10⁷
Therefore, By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.
