Need help with this math problem...

5x=$105

Each ticket costs $21.

Step-by-step explanation:

1). Since he bought 5 tickets and he paid $105 your equation will look like this(keep in mid your x is = tickets so your equation is basically saying he bought 5 tickets for $105):

          5x = 105

2). You divide by 5 and you get x =21.

slope = -

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 9) and (x₂, y₂ ) = (3, 5)

m = = = -
