Which equation represents a line that passes through (-9,-3) and slope of -6
Scilla [17]

Answer:

y + 3 = -6(x + 9) or y = -6x - 57

Step-by-step explanation:

We can use the point-slope form for this situation.

Point-slope form: y - y₁ = m(x - x₁), where m = slope and (x₁, y₁) are given coordinates.

Plug in: y + 3 = -6(x + 9)

This can be changed to the more common slope-intercept form.

Multiply: y + 3 = -6x - 54

Subtract: y = -6x -57

A drama club earns $1040 from a production. It sells a total of 64 adult tickets and 132 student tickets. An adult ticket costs
ASHA 777 [7]
Adult ticket = x
student ticket = y

<span>An adult ticket costs twice as much as a student ticket. 
</span>x = 2y

Total earnings is $1040
64x + 132y = 1040 

x = 2y ------------------------------ (1)
64x + 132y = 1040  -------------(2)
Sub (1) into (2)
64 (2y) + 132y = 1040
128y + 132y = 1040
260y = 1040
y = 4 ------- sub into (1)
x = 2(4) = 8

Student ticket = $4
Adult ticket = $8
