We can put it into point slope form first, y-y1=m(x-x1), where m is the slope and (x1,y1) is any point on the line.
y--7=(-2/3)(x-0)
y+7=-2x/3, slope intercept form is y=mx+b, so we simply need to solve for y.
y=-2x/3-7
Answer:
x = 6 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2+ x^2 = 12^2
36 + x^2 = 144
Subtract 36 from each side
x^2 = 144-36
x^2 =108
Take the square root of each side
sqrt(x^2) = sqrt(108)
x = sqrt(36*3)
x = 6 sqrt(3)
I'm pretty sure that it would be 1/2 since it says 1/3 each whole, which in this case it would be 1/3 each hour.
If y is 7, x is 2. If y is 9, x is 4. Therefore the domain is {2,4}
