Answer:
y = x - 5
Step-by-step explanation:
y - y_1 = m(x - x_1)
First find the slope of the line
y = x - 1
y = mx + C
y - intercept point y
m - slope
x - intercept point x
C - intercept of the line
y = x - 1
The slope for the eqn is 1
Then we can use the eqn of line
y - y_1 = m(x - x_1)
Using the point we are provided with
( 4, -1)
x_1 = 4
y_1 = -1
y - (-1) = 1(x - 4)
y + 1 = 1(x - 4)
open the bracket
y + 1 = x - 4
y = x - 4 -1
y = x - 5
Therefore, the slope (m) of the line is 1
And the equation of the line is
y = x - 5
