Question

Graph the line y=kx+1 if it is known that the point M belongs to it: b M(2, −7)

Answer 1

Answer:

y=-4x+1

Step-by-step explanation:

So you can put one point on (1,-3) and another point on (2,-7) and then make a line.

Answer 2

Answer:

Step-by-step explanation:

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

$-7 = 2\cdot k +1$

$2\cdot k = -8$

$k = -4$

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