Answer:
y = 3x + 1
Explanation:
Slope Intercept form is written out as the following:
y = mx + b
In order to convert "3x - y = -1", we first subtract 3x from both sides, giving us:
-y = -3x - 1
Since we have "-y", we multiply -1 on both sides.
-1(-y) = -1(-3x - 1)
Multiplying two negatives makes a positive, hence when we multiply -1 on both sides, it becomes this:
y = 3x + 1
So converting to the Slope Intercept form ends up being "y = 3x + 1"
