Need help with 2,3,4

Answers:

In these exercices are ilustrated the representations of the fractions

2) Firstly, we have 3 equal segments, each one representing \frac{1}{4}, hence:

\frac{3}{4} is <u>3</u> copies of \frac{1}{4}

Let's prove it, taking into account we are adding fractions with the same denominator:

\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}

There are <u>4</u> equal parts that make a whole

Four copies of <u>\frac{1}{4}</u> make \frac{4}{4} or <u>1</u> whole

\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{4}{4}=1

3) Here we have a line divided into four segments, each one of \frac{1}{5}. Hence:

This is \frac{4}{5} of a line. \frac{4}{5} is <u>4</u> lengths of  \frac{1}{5}

\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}=\frac{4}{5}

If we draw one more \frac{1}{5} we will have \frac{5}{5} or 1 whole.

Then:

<u>5</u> lengths of \frac{1}{5} make \frac{5}{5} or <u>1</u> whole.

4) In this part the answer is in the attached image. If we have two equal segments, each one of \frac{1}{3} we will have as a result \frac{2}{3}.

If we add another \frac{1}{3} segment, we will have three segments of \frac{1}{3}, having as a result \frac{3}{3}=1

Write the equation in y=mx+b form please????
Solnce55 [7]

ANSWER

y =  - 2x - 5

EXPLANATION

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

m =  \frac{y_2-y_1}{x_2-x_1}

This implies that;

m =  \frac{5 - 1}{ - 5 -  - 3}

m =  \frac{4}{ - 2}  =  - 2

We can now find the equation using the formula;

y-y_1=m(x-x_1)

y   - 1 =  - 2(x  + 3)

Expand:

y =  - 2x -6 + 1

y =  - 2x - 5
