Answer:
40
Step-by-step explanation:
use slope formula (4-12)/(7-21) = 8/14 (8/14)*70 = 40
Se necesitan los puntos que representen a Y1 y X1, si no no te puedo ayudar solo te puedo dar la formula
La formula para la ecuación es:
(Y-Y1)=m (X-X1)
Add 6 to both sides so that you can get the variable by itself
Step-by-step explanation:
In a direct proportion, the ratio between matching quantities stays the same if they are divided. (They form equivalent fractions). In an indirect (or inverse) proportion, as one quantity increases, the other decreases. In an inverse proportion, the product of the matching quantities stays the same.
