Answer:
2: x = 2y + 6
3: The y-intercept
4: 12
Step-by-step explanation:
2:
y = 1/2x - 3
Add 3 to both sides -> y (+ 3) = 1/2x - 3 (+ 3)
y + 3 = 1/2x
Divide both sides by 1/2 or multiply both sides by 2 -> y + 3 (x 2) = 1/2x (x 2)
2y + 6 = x
3: The y-intercept is the value that satisfies x = 0, or wherever the line crosses the y-axis
4: The y-intercept in an equation is always the value after x (aka the initial value)
