What is the slope of the line that is parallel ^

Given:

Given that the equation of the line is

We need to determine the slope of the line.

Slope:

The general form of the equation of the line is where m is the slope of the line.

Comparing the equation with the general form of the equation of the line, we get;

Slope = m = 2.

Hence, the slope is 2.

Since, we need to determine the slope of the parallel lines and we know that the slope of the parallel lines are equal.

Thus, the slope of the parallel line is 2.

Hence, Option B is the correct answer.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
