PZ ITS URGENTTT Q2: Find the gradients of each of the following lines. /8
L1 (b) L2 (c) L3 (d) L4

a)It is a vertical line with an undefined slope

b)It is a vertical line with an undefined slope

c)7/4

d)-7/4

Step-by-step explanation:

The formula for gradient of a line is given as;

m=Δy/Δx

where Δy = y₂-y₁   and Δx=x₂-x₁

For L₁

x=2

It is a vertical line with an undefined slope

For L₂

x=-3

It is a vertical line with an undefined slope

For L₃

The points on the line are : (0,-3)  and (4,4)

m= Δy/Δx

m= 4--3/4-0

m=7/4

For L₄

The points on the line are : (0,-3) and (-4,4)

m=Δy/Δx

m=4--3/-4-0

m=7/-4

m= - 7/4

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

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.
