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

the answer is d

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
