you simply substitute the coordinates into the given equation

so
-7 = 3k + 2

then solve from there
-9 = 3k

-3 = k

Answer:

k=-3

Step-by-step explanation:

The given equation of line is

[tex]y=kx+2[/tex]

We need to find the value of k if the above line passes through the point C(3,-7).

If a line passes through a point, then the equation of line must be satisfy by that point.

Substitute x=3 and y=-7 in the given equation.

[tex]-7=k(3)+2[/tex]

Add 2 on both sides.

[tex]-7-2=3k+2-2[/tex]

[tex]-9=3k[/tex]

Divide both sides by 3.

[tex]-3=k[/tex]

Therefore, the value of k is -3.
