Answer:
y = 4x - 9
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"
The slope we can do rise over run "r/r" ot "y/x"
r/r = 4/1 = 4
The line is positive since its going up
y = 4x - 9
Hope this helped!
Have a supercalifragilisticexpialidocious day!
The addition property of equality is the idea we can add some number to both sides of an equation. You must add the same number to both sides to keep things balanced.
It's asking "what number can we add to both sides of this equation so that we isolate x?"
Think of 20+x as x+20. We can rearrange terms since adding in any order doesn't matter (eg: 2+3 = 3+2 = 5)
So we really have this equation: x+20 = 25
We can add -20 to both sides to cancel out the +20 on the left side
x+20 = 25
x+20+(-20) = 25+(-20) ...... add -20 to both sides
x = 5
This is the exact same as subtracting 20 from both sides. So 5 will go where x is, meaning that 20+x = 20+5 = 25
Answer:
-45
Step-by-step explanation:
Look at the x-value column to row -15, and then look over to the y-value column for an answer of -45.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

To know if they are proportional check to see if there is a number common to the relationship between the y and x to all the numbers:
10/2=5
15/3=5
20/4=5
25/5=5
There is a relationship of 5 and the 5 is multiplied to the x=boxes.
Yes, because the price is 5 times the number of boxes
I think the answer is B hope this helps
