Therefore, the answer is 1) y = 2x - 6
Answer:

Step-by-step explanation:
Given: 
Since the equation is written in slope-intercept form, it is extremely easy to find the y-intercept. Slope-intercept form is written as:

Whereas:
y: range
m: slope
x: domain
b: y-intercept
With that in mind, we can immediately tell that 6 is the y-intercept.
Answer:
Step-by-step explanation:
y + 4 = 0(x - 2)
y + 4 = 0
y = -4
