Hey there :)
To find the slope with <em>two points</em> we will need to use the equation 

( 3 , -20 ) ( 5 , 8 )
Here is what the equation should look like when replaced with the numbers (<em>it will be a fraction</em>) :

We know that <em>two negatives</em> cancel out and make a positive, so the numerator would actually be 8 + 20.
Solve the fraction and we get 
28 <em>divided</em> by 2 is 14. The slope is 14.
Answer:
20
step by step explanation:
Complementary I’m sure but I could be wrong
Answer:
thus, the ratios 8 : 16 and 6 : 12 are equal
Step-by-step explanation:
8 : 16 and 6: 12
8 : 16 = 1/2
6: 12= 1/2
Thus, the ratios 8 : 16 and 6 : 12 are equal
Let's say x=cherries and y=grapes. (desmos only does x and y :( ).
the equation would be 9=4x+1.50y
