We should change this equation to the slope-intercept form first. y = mx + b
So all we have to do is move the term with the x variable in it to the other side by adding it (inverse of a negative).
-2x - 4y = -20
+2x on both sides
-4y = 2x - 20
Now, we divide the whole thing by -4 to get y alone.
y = -1/2x + 5
To calculate for y, we must set x to 0.
y = 0x + 5
y = 5
To calculate for x, we must set y to 0.
(0) = -1/2x + 5
Move 5 by subtracting 5 to both sides.
-5 = -1/2x
Now we have to get x alone, to do that, we must divide by -1/2 on both sides.
10 = x
Answers:
y = 5
x = 10

Since <span>using ≤, ≥</span>, it means that the lines are included, the line is graphed as a solid line. When you have plain > or <, the line is not included, so you use a dashed line.
Answer:
8 tickets
Step-by-step explanation:
To find how many she can buy, divide 36 by 4.5
36/4.5
= 8
So, Mai can buy 8 movie tickets
Answer: The answer is -50
because 80 + -50 = 30 and 30 + -30= 0 .
The answer would be <span> inch, foot, yard, and mile</span>.
