Answer:
1.5
Step-by-step explanation:
the slope is regarded as :
= [tex]\frac{y2-y1}{x2-x1}[/tex]
this is also known as the gradient , meaning the differences of two y values divided by the differences of the two corresponding x values
take two values on the slope and put in the form ( x,y)
we shall use two points A and B
A = (80 , 100)
B = (20 , 10)
now use the formula:
[tex]\frac{10-100}{20-80}[/tex]
=[tex]\frac{-90}{-60}[/tex]
= [tex]\frac{3}{2}[/tex]
also can be represented into an integer form
answer is 1.5
