7 Consider the line y=-x-5.
x-s.
Find the equation of the line that is perpendicular to this line and passes through the point (4, 6).
Find the equation of the line that is parallel to this line and passes through the point (4, 6).

y = x + 2

Step-by-step explanation:

1.) identify the gradient in the given equation

M1= -1

2.) use the formula to find the next gradient

formula: M1 × M2 = -1

-1 × M2 = -1 ( divide by -1 on both side)

M2 = 1

3.)use the formula

y - 6 = 1 ( x- 4)

y - 6 =1x -4(add 6 on both side)

y = x + 2

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.

answer: i think one of the answer is $150 and $300?
