Answer:

90%

Step-by-step explanation:

% itself means out of 100 so yea:

18/20 times 100

1800/20

90/100

90%

Another way u could do is just multiply a number that would make 20 into 100, so:

(18/20)5/5

90/100 = 90%

I'd appreciate your guys' help! :)
butalik [34]

Point slope form is :

8+12 = m(9-4)

8+12= 9m -4m

20= 5m

20/5= 5m/5

m= 4

Slope form

Slope of M(-2, 3), N(7 -4)
Mila [183]

Answer:

-\frac{7}{9}

Step-by-step explanation:

We find slope by; change in y ÷ change in x,

Change in y = -4 - 3 = -7

Change in x = 7 - - 2 = 9

Slope of line MN = -7 ÷ 9 = -\frac{7}{9}
