Answer:
Step-by-step explanation:
<u>Use the slope formula:</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = -3, x₁ = 4, y₁ = r, x₂ = 8, y₂ = -11
<u>Substitute values and solve for r:</u>
- -3 = (-11 - r)/(8 - 4)
- -3 = -(11 + r)/4
- 11 + r = 12
- r = 12 - 11
- r = 1

Answer:
3 - 6 = -3(1 - 0)
Step-by-step explanation:
To write an equation of point-slope from two points, first you need the slope.
To find slope, find the change in y over the change in x.
- (0,6) y = 6 and x = 0
- (1,3) y = 3 and x = 1
The change in y over change is x means (y2 - y1) / (x2 - x1)
change in y: -3
change in x: 1
slope = -3/1 or -3
Now that we have slope we can start the point-slope equation.
Point-slope equation: y2 - y1 = m(x2 -x1)
[<em>m</em><em> </em>means slope]
Finally, the point slope equation for these points is: 3 - 6 = -3(1 - 0)
Answer:
15 business class and 12 economy class
Step-by-step explanation:
15 + 12 = 27
15 * 700 = 10500
12 * 375 = 4500
$10500 + $4500 = $15,000
