D. y=−3x+2

Step-by-step explanation:

We know that equation of a line passing through points (x_1,y_1) and (x_2,y_2) is

$(y-y_1)=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Thus equation of line passing through points(1,-1) and (-1,5) is

$(y-(-1))=\frac{5-(-1)}{-1-1}(x-1)\\\Righatrrow(y+1)=\frac{6}{-2}(x-1)\\\Rightarrow(y+1)=-3(x-1)\\\Rightarrow\ y+1=-3x+3\\\Rightarrow\ y=-3x+2$

Thus D is the right answer.

The equation of the line given by graph is y=−3x+2

The converse would be

If the 2 angles are equal in measure the each of the 2 angles has a measure of 28 degrees.

AS you see in this example , the converse is not necessarily true.
