Step-by-step explanation:

Since line e is perpendicular to line d, the slope for line e would be the inverse of line d.

Therefore, the slope of e would have to be .

When lines are perpendicular inverse the slope.

When lines are parallel the slope stays the same but the y-intercept changes.

I hope this helps!!

question:

could we have options?

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.
