Answer:
m= -1/2
Step-by-step explanation:
Parallel lines have the same slope, so find the slope between the 2 points.
0 - ( -1 ) / -6 - ( -4) = 1/-2
[tex]\\ \bull\tt\dashrightarrow Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\\ \bull\tt\dashrightarrow Slope=\dfrac{0+1}{-6-4}[/tex]
[tex]\\ \bull\tt\dashrightarrow Slope=\dfrac{1}{-10}[/tex]
