Which best describes the relationship between the line that passes through the points (-6, -1) and (-11, 1) and the line that passes thre the points (-3, -8) and (-5, -13)?

B. They are perpendicular

Step-by-step explanation:

calculate the gradient of (-6, -1) and (-11, 1)

m= y2 - y1/ x2 - x1

= 1 - (-1)/ -11 -(-6)

m = -2/5

then you find the gradient of the other points in the same way

m = y2 - y 1/ x2 -x1

= -13 -(-8)/ -5 -(-3)

m = 5/2

to prove that they are perpendicular

m1×m2 = -1

-2/5 × 5/2 = - 1

hence they are perpendicular

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
