Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)

Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)

Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.

<u>Answer:</u>

Yes

<u>Step-by-step explanation:</u>

In above image use vertical line test to identify whether a relation is a function or not . Vertical line test means draw various vertical lines in graph and it must cut graph only once i.e. every vertical line must intersect graph only once . if lines intersects graph in more than 1 point than relation is not a function . In short, a relation is a function iff for every value of x there's only one value of y , for any case x has 2 or more than 2 values of y it's <u>not a function.</u>

Ugo [173]

Answer:

According to the passage, whales weight 300,000 pounds on average. Narwhales weigh 2,000 pounds on average.

Step-by-step explanation:

Since the question is extremely vague, I'll just answer what's the weight of whales and the weight of narwhals.

According to the paragraph, blue whales weigh 3×10^{5} pounds.

This is what we call scientific notation. You could solve it normally, or you could use a faster method.

Scientific notation states that the first number that you see, the three, is the first part of the answer. The exponent on the number of zero's that there is.

That means that the answer to 3×10^{5} you get 300,000.

Let's do the same thing to Narwhales.

2×10^{3} is 2,000.
