Hi!
<h3>The equation of point slope form is</h3>
<u>y = sx + b</u>
We need to find s and b
s = slope
b = y intercept
-------------------------------
<h3>To find the slope, use this formula. </h3>
Put in the values.
The slope is 2.
<u>y = 2x + b</u>
------------------------------------
<h3>Now we need to find the y intercept. Put in a point, and solve for b. </h3>
-8 = 2 * -6 + b
-8 = -12 + b
4 = b
The y intercept is 4.
<u>y = 2x + 4</u>
<h2>The answer y = 2x + 4</h2>
Hope this helps! :)

Answer:
Step-by-step explanation:
Let
y -----> gallons of water remaining in the barrel
x-----> number of minutes elapsed
we know that
Water leaks out of the barrel at a rate of 1 gallon every 10 minutes
so
The linear equation that represent this situation is
The graph in the attached figure
Answer: probability of having a green apple would be 2/5. The probability of picking a red apple would be 3/5.
Step-by-step explanation: there are 10 apples in total. So it would be 4/10 and 6/10
Since the events are dependent, the probability of occurrence of event B will impact the probability of occurrence of event A. So we will be using the formula of conditional probability to find P(A ∩ B).
Here P(A*B) indicates P(A ∩ B).
Using the values, we get:
P(A ∩ B) = 0.25 x 0.4 = 0.1
Thus, option A gives the correct answer.
Step-by-step explanation:
Split the figure into 2 parts, triangle and rectangle (I believe you know what I'm talking about)
area of triangle = 1/2 x 20 x (16-7) = 90cm^2
area of rectangle = 20 x 7 = 140cm^2
total area = 90 + 140 = 230cm^2
