Answer:

slope = \frac{2}{3}

Step-by-step explanation:

To find the slope of a line, use the slope formula, \frac{y_2-y_1}{x_2-x_1}. x_1 and y_1 represent the x and y values of one point on the line, and x_2 and y_2 represent the x and y values of another point on the line.

So, this formula requires two points from the line. Reading the graph, we can see that the two points marked on the line are (-3,-4) and (3,0). Thus, use the x and y values of those two points, substitute them in the appropriate order into the formula, and solve:

\frac{(0)-(-4)}{(3)-(-3)} \\= \frac{0+4}{3+3} \\= \frac{4}{6} \\= \frac{2}{3}

Therefore, the slope of the line is \frac{2}{3}.

Add and simplify 9/16 + 1/2 =
harkovskaia [24]

\boxed{\boxed{ \ \frac{9}{16} + \frac{1}{2} = \frac{17}{16} = 1\frac{1}{16} \ }}

<h3>Further explanation</h3>

We will work on adding two fractions correctly with different denominators. The two denominators must be equated first.

In order to add these fractions, we need finding the common denominator by multiplying both denominators together.

\boxed{\frac{9}{16} + \frac{1}{2} = \ ?}

Both denominators, 16 and 2, are multiplied by one another. What about numerators? Pay attention to the treatment of each fraction.

\boxed{= \big( \frac{9}{16} \times \frac{2}{2} \big) + \big( \frac{1}{2} \times \frac{16}{16} \big)}

\boxed{= \frac{18}{32} + \frac{16}{32}}

\boxed{= \frac{34}{32}}

Let's take a break here to think.

Alternatively, develop a sharper method as below.

\boxed{= \frac{(9 \times 2) + (16 \times 1)}{16 \times 2}}

Note how this is performed. Absolutely indeed, cross-multiplication!

\boxed{= \frac{18 + 16}{32}}

\boxed{= \frac{34}{32}}

The numerator and denominator are divided by two to make it a simple fraction. After that, we simplify again into mixed fractions.

\boxed{\boxed{ \ \frac{9}{16} + \frac{1}{2} = \frac{17}{16} = 1\frac{1}{16} \ }}

Gently let's take a break once more to think strategically.

Observing the steps above, we still find a large number when there is a direct multiplication of the two denominators. Are there more highly recommended steps? Of course there is!

\boxed{\frac{9}{16} + \frac{1}{2} = \ ?}

The denominators 2 and 16 have LCM = 16. So, we convert the given fractions into equivalent fractions with denominator 16.

\boxed{= \big( \frac{9}{16} \times \frac{1}{1} \big) + \big( \frac{1}{2} \times \frac{8}{8} \big)}

\boxed{= \frac{9}{16} + \frac{8}{16}}

\boxed{= \frac{17}{16}}

Do not forget simplifying again into mixed fractions.

\boxed{\boxed{ \ \frac{9}{16} + \frac{1}{2} = \frac{17}{16} = 1\frac{1}{16} \ }}

<u>Note:</u>

In the form of fractions, the steps that must be considered are

  • equate the denominator,
  • simplify fractions, and
  • for the final answer, convert fractions to mixed fractions or decimal forms
