A line passes through the point (-9,3) and has a slope of -2/3?
saveliy_v [14]

The point-slope form:

y-y_1=m(x-x_1)

We have the slope m = -2/3 and the point (-9, 3). Substitute:

y-3=-\dfrac{2}{3}(x-(-9))

y-3=-\dfrac{2}{3}(x+9)      <em>use distributive property</em>

y-3=-\dfrac{2}{3}x-\dfrac{2}{3}\cdot9

y-3=-\dfrac{2}{3}x-(2)(3)

y-3=-\dfrac{2}{3}x-6     <em>add 3 to both sides</em>

\boxed{y=-\dfrac{2}{3}x-3}

What's the simplest form of 10/1​
kupik [55]

Answer:

1 s / 6 s

Step-by-step explanation:

Since you have different units of measurement (seconds and minutes) you have to get them to be the same unit.

Change the 1 minute into seconds.

1 min = 60 sec

Now simplify the new fraction.

10 s / 60 s

10 can go into both the numerator and the denominator.

1 s / 6 s
