Answer:
gradient = - 
Step-by-step explanation:
Calculate the gradient m using the gradient formula
m = 
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (3, 1) ← 2 points on the line
m =
=
= -

7x+4 is the correct awnser(i think)
Answer:

Step-by-step explanation:
Given
Shape: Circle
Required
The area and the circumference (relationship)
This implies that, we write an expression that relates the area and the circumference.
Circumference is calculated as:

Area is calculated as:

The area can be rewritten as:

Further rewrite as:

Recall that:
So, the expression becomes


Y=k/x
2.5=k/6
k=15
wheny x=4, y=15/4
y=3.75
