D. y=-2x-1

Step-by-step explanation:

We have been given a line on coordinate plane. We are asked to find the equation of our given line.

First of all, we will find slope of our given line using points (-2,3) and (0,-1) in slope formula.

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

y_2-y_1 = Difference between two y-coordinates,

x_2-x_1 = Difference between two x-coordinates of same y-coordinates.

Upon substituting our given values in slope formula, we will get:

$m=\frac{-1-3}{0--2}$

$m=\frac{-4}{0+2}$

$m=\frac{-4}{2}$

m=-2

Now, we will use slope-intercept form of equation y=mx+b , where,

m = Slope of line,

b = The y-intercept.

Upon looking at our given graph, we can see that y-intercept is .

Therefore our required equation would be y=-2x-1 and option D is the correct choice.
