Hey there!!
How do you find slopes?
Ans - In order to find slope, we will need to use the slop formula which is
( y₂ - y₁ ) / ( x₂ - x₁ )
Now let's take two points on the graph :
I would take the coordinates ( 0 , -1 ) and ( 1 , 4 )
y₂ = 4 , y₁ = -1 and x₂ = 1 , x₁ = 0
( 4 + 1 ) / ( 1 - 0 )
5 / 0
Hence, the slope is equal to 5
Hope my answer helps!!
Answer:
85% decrease
Step-by-step explanation:
The percentage change is the change fraction multiplied by 100%.
percent change = change / original × 100%
= (3 -20)/20 × 100%
= -17/20 × 100% = -85%
A decrease from £20 to £3 is a change of -85%.
