This is how it is done. Let me know if you have questions...
Answer:
y=4/9
Step-by-step explanation:
Substitute 2y into the x
2(2y)+5y=4
4y+5y=4
9y=4
y=4/9
Your equation would be:
D. y = 10x + 6
Y= 1x+ 3
1x is the slope and 3 is the y intercept
I did rise over run to find the slope 3/3=1
Y is 3 because y intercept is when a line go through the y axis and it’s on 3
hope this helps!
Multiply 2/1 or 2 on both sides to get "y" by itself

y ≤ -14
