Answer:

Step-by-step explanation:

Let be [tex]y = k\cdot x +1[/tex] the expression of the line, where [tex]x[/tex] and [tex]y[/tex] are the independent and dependent variables, respectively. If we know that [tex]x = 2[/tex] and [tex]y = -7[/tex], the value of [tex]k[/tex] is:

[tex]-7 = 2\cdot k +1[/tex]

[tex]2\cdot k = -8[/tex]

[tex]k = -4[/tex]

The equation of the line is [tex]y = -4\cdot x +1[/tex], which is graphed below.

Equation of line:

Given that equation of line is,

                       [tex]y=kx+1[/tex]

since, line passes through [tex]M(2,-7)[/tex].

Substitute point  in given equation of line.

                   [tex]-7=2k+1\\\\2k=-8\\\\k=-8/2=-4[/tex]

So that, equation of line becomes,   [tex]y=-4x+1[/tex]
