Find the slope of the line perpendicular to the line containing (0,0) and (-1,4).

Hello, Have a good day

Step-by-step explanation:

The slope of the perpendicular line is the opposite sign and the inverse of the original line's slope.

(-1,-2) and (0,0).

slope = (0 - -2)/(0 - -1) = 2/1

So ,inverse and opposite would be -1/2

A parallel line has the same slope with a different y intercept

-2 = (-1/2)(-1) + b

-2 = 1/2 + b

b = -5/2

So, same slope, different b (y intercept) for a parallel line.

10% of increase is the final 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.
