Question

the slope of the line below is -1/7. Write the point slope equation of the line using the coordinates of the labeled point

Answer 1

C. The formula is y-y sub1= m (x-x sub1)

Answer 2

Answer:

The correct option is C.

Step-by-step explanation:

If a line passes through the point $(x_1,y_1)$ with slope m, then the point slope form of the line is

$y-y_1=m(x-x_1)$

It is given that the slope of the line is -1/7. From the graph it is clear that the line passes through the point (3,3).

Substitute x₁=3, y₁=3 and $m=-\frac{1}{7}$ in the above equation.

$y-3=-\frac{1}{7}(x-3)$

The point slope form of the given equation is $y-3=-\frac{1}{7}(x-3)$.

Therefore the correct option is C.
