Question

Can someone help please

Answer 1

Coordinate points on line(-3,-1) and (3,3)

Parallel lines have same slope
so 
m = (3+1)/(3+3) = 4/6 = 2/3

Answer
B. 2/3

Answer 2

To compute the slope of a line that passes by two ponits A and B we use the formula : 
$m=\dfrac{y_B-y_A}{x_B-x_A}$
Use this formula to answer your question.
