Write an equation for the line (4,7) and ( 1,1)2. Write an equation for the graph

Nastasia [14]

ANSWER:

$y=2x-1$

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope-intercept form is the following:

$\begin{gathered} y=mx+b \\ m\text{ is the slope and b is the y-intercept } \end{gathered}$

The slope can be calculated as follows:

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

We use the points (4,7) and (1,1) to calculate the slope:

$m=\frac{1-7}{1-4}=\frac{-6}{-3}=2$

Now, we calculate the value of b, using the point (1,1) and the slope, like this:

$\begin{gathered} 1=1\cdot2+b \\ b=-2+1 \\ b=-1 \end{gathered}$

Therefore, the equation would be:

$y=2x-1$

How to get rid of fraction exponents?. for example: x^(1/2)

Komok [63]

Remember
$x^{ \frac{m}{n} }= \sqrt[n]{x^m}$

so
$x^{ \frac{1}{2} }= \sqrt[2]{x^1}$ or √x

What is the disturbited property of (-2.5)(3-8y)

Mars2501 [29]

<u><em>Answer: =-7.5+20y</em></u>

Step-by-step explanation:

distributive property: a(b+c)=ab+ac

a=-2.5, b=3, c=8y

-2.5*3-(-2.5)*8y

3(-2.5)-8(-2.5)y

simplify by equation.

3(-2.5)-8(-2.5)y=-7.5+20y

=-7.5+20y

Hope this helps!

Thanks!

Have a great day!
