The simpliest way to do this is to turn both fractions into decimals
7/10 goes to 0.7 and 2/5 goes to 0.4
then the equation would be 0.7x + 20 = 0.4
hope I've helped!

Answer:
a=1/3
Step-by-step explanation:
from the point on the graph
x=4 and y=8
substitute them into the equation:
y=a(x-2) (2x+4)
you will get
8=a(4-2) (2(4)+4)
8=a(2) (8+4)
8=a(2) (12)
8=2a×12
8=24a
divide both sides by 24
8/24=24a/24
1/3=a or a=1/3
Answer:
