Plz help me out:( :(

Look below

Step-by-step explanation:

To figure whether a line is perpendicular or parallel check the slopes

When a line is parallel the slopes are the same

When a line is perpendicular the slopes are negative reciprocals

40. Neither (They aren't the same nor a negative reciprocal)

41. Neither (When you put y on the left it isn't a reciprocal)

42. Parallel (The slopes are both -3/2)

To do 43-44 make sure that the slopes are the same then plug in the points to to find the y-intercept (make sure you solve for b)

43. y = -4x - 1

44. y = 2x + 1

For 45-46 do the same thing, but make sure you change the slope to a negative reciprocal since its perpendicular

45. y = -3/2x-11

46. y = 1/4x+4

step-by-step explanation:

i hope this you : d

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
