Which equations represent the line shown in the graph?

Choose all answers that are correct.

What you would need to do is to find the equation given the two points. Firstly, lets find the slope of the equation
$$m=\frac{y_1-y_2}{x_1-x_2}$$
Where $(x_1,y_1)$ is one co-ordinate, and $(x_2,y_2)$ Is another co-ordinate. Here, lets make:

$(x_1,y_1)$=(3,2)
$(x_2,y_2)$=(-2,-1)

Lets sub these values into the equation:
$$m=\frac{y_1-y_2}{x_1-x_2}$$
$$m=\frac{2-(-1)}{3-(-2)}$$
$$m=\frac{3}{5}$$

Now, we know that the basic equation is
$$y-y_1=m(x-x_1)$$
So now, lets sub in the values we know
$$y-y_1=m(x-x_1)$$$$y-3=\frac{3}{5}(x-2)$$
That is the same as the first one you showed, so thats the answer
