What equation is graphed in this figure? y−4=−13(x+2) y−3=13(x+1) y+2=−3(x−1) y−5=3(x−1) Number graph ranging from negative four

omeli [17]

Answer: The correct option is 3.

Explanation:

It is given that the line passes through (-1,4) and (1,-2).

The slope of the line is,

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of the given line is,

$m=\frac{-2-4}{1-(-1)} =\frac{-6}{2}=-3$

The point slope form of a line is,

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

Where, m is the slope.

Since slope is -3 and point is (-1,4), then the equation of line is,

$y-4=-3(x+1)$

Since slope is -3 and point is (1,-2), then the equation of line is,

$y+2=-3(x-1)$

Therefore, the correct option is 3.
