Answer:

y + 1 = - 7(x - 1)

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 7 and (a, b) = (1, - 1), thus

y - (- 1) = - 7(x - 1), that is

y + 1 = - 7(x - 1)

Answer:


y+1=-7(x-1)

Explanation:

Pre-Solving

We are given that a line has a slope (m) of -7 and contains the point (1,-1).

We want to write the equation of this line in point-slope form.

Point-slope form is given as
y-y_1=m(x-x_1) where m is the slope and
(x_1,y_1) is a point.

Solving

As we are already given both the slope and the point, we can plug their values into the equation.

Starting with the slope, replace m with -7.


y-y_1=-7(x-x_1)

Now, substitute 1 as
x_1 and -1 as
y_1.

We get:


y--1=-7(x-1)

This can be simplified to become:


y+1=-7(x-1)
