Z varies jointly with x and y. when x=2 and y=3, z=60. what is the value of z when x=4 and y=9?
laiz [17]
<span>Z $ xy then Z = Kxy. When x = 2 and y = 3, and Z = 60, our constant of variation becomes 60 = K * 2 * 3 K = 10. Our constant of proportionality equals 10. We would need that in the second part of the equation. When x = 4 and y = 9, we have Z = 10 * 4 * 9 = 360</span>

Write an equation of the line passing through points (3,8) and (-2,-22)
Gala2k [10]

Answer:

y=6x-10

Step-by-step explanation:

First, we can find the slope using the two given points.

m=\frac{y2-y1}{x2-x1}=\frac{-22-8}{-2-3}=\frac{-30}{-5}=6

Then, we can use the slope we just found and one of the given points to find the y-intercept.

y=mx+b\\y=6x+b\\8=6(3)+b\\8=18+b\\b=-10

And we can put our equation together.

y=6x-10

Hope this helps!
