We have to express the ratio 1 : 3.5 in the form p:q where p and q are whole numbers.
Consider the ratio of 1 and 3.5,
1 : 3.5 =
=
Reducing the above fraction to its lowest form.
So, we get
Therefore, the ratio 1 : 3.5 is expressed as
where 2 and 7 are the whole numbers.
Answer:
slope =
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line
m = =
=
