Write the equation in slope-intercept form for the line that passes through the given point
ASHA 777 [7]

Answer:

y=x+4

Step-by-step explanation:

2y=2x+4 simplifies down to y=x-2. Since the two lines are parallel, they have to have the same slope, but different y-intercepts. This means that we just have to find the y-intercept that will allow our line to pass through (-5, -1).

If we input the coordinates into what of our equation we have thus far (y=x+b), we just have to find what b needs to equal to make the equation true.

-1=-5+b                  -1=-5+4

b = 4                     -1=-1
