What is the slope of the following graph? (write your answer as a fraction unless divided by 1. Do not use spaces in your answer

alexira [117]

The slope of the graph is 4/5

<h3>How to determine the slope</h3>

Using the formula

Slope = Δ y-axis / Δ x- axis

y2 = -4

y1 = 0

x2 = -5

x1 = 0

Slope = $\frac{y2 - y1}{x2 - x1}$

Substitute the values into the formula

<em>Slope = </em> $\frac{-4 - 0}{- 5 - 0}$

Slope = $\frac{-4}{-5}$

Slope = $\frac{4}{5}$

Therefore, the slope of the graph is 4/5

Select the correct responses in the table. The relationship between two numbers is described below, where x represents the first

Answer:

x² = y + 16
4y - 1 = 7x
(5, 9)

Step-by-step explanation:

Writing equations from words is mostly a matter of understanding what the English words mean.

If the first number is x, then the square of the first number is x². That is said to be equal to the sum of the second number (y) and 16:

x² = y + 16 . . . . the first equation

The wording "the difference of A and B" is usually intended to be interpreted to mean A-B. Here, we have the difference of 4 times the second number (4y) and 1, so ...

4y -1

This is equal to the first number (x) multiplied by 7, so ...

4y -1 = 7x . . . . the second equation

These can be solved a variety of ways. When no method is specified, I like to use a graphing calculator. It shows the only integer solution for this pair of equations is ...

(x, y) = (5, 9)

An acute triangle might have interior angles that measure:

igor_vitrenko [27]

Answer:

50, 50, 80.

Step-by-step explanation:

An acute triangle is defined as a triangle with no interior angle larger than 90 degrees. Knowing this, and the fact that the interior angles of a triangle add up to 180 degrees, we can assume that 50, 50, and 80 are three angles that could make up an acute triangle.
