Can someone please help me !

Answer:

A = \frac{5}{6}

Step-by-step explanation:

From the number line attached in the figure,

Number of small parts from number 0 to 1 on the given number line = 6

A is the point which lies at 5th part from 0.

Each small part represents the fraction = \frac{1}{6}

Therefore, A represents the fraction = 5\times \frac{1}{6}

                                                             = \frac{5}{6}

So A = \frac{5}{6} will be the answer.

Through: (-5, -5), slope=2/5
kakasveta [241]

For this case we have that by definition, the equation of a line in the slope-intersection form is:

y = mx + b

Where:

m: It is the slope

b: It is the cut point with the y axis

The slope is: m = \frac {2} {5}

Thus, the equation is of the form:

y = \frac {2} {5} x + b

We substitute the given point and find "b":

-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3

Finally, the equation is:

y = \frac {2} {5} x-3

Answer:

y = \frac {2} {5} x-3
