Answer:
The answer to your question is y = x - 5
Explanation:
Data
Point = (4, -1)
line ║ to y = x - 1
Process
1.- Find the slope. The slope is the coefficient of the x.
y = 1x - 1
slope = m = 1
2.- Identify the values x1 and y1
x1 = 4 y1 = -1
3.- Find the equation of the line
y - y1 = m(x - x1)
-Substitution
y + 1 = 1(x - 4)
-Solve for y
y + 1 = x - 4
y = x - 4 - 1
-Result
y = x - 5
