Write an equation for the line that passes through (4,-6) and (-7,-6). Is the line parallel or perpendicular to the y-axis?

alisha [4.7K]

Answer:

y = -6, perpendicular

Step-by-step explanation:

You can use the points to find the slope of the line:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{-6-(-6)}{-7-4} =\frac{-6+6}{-7-4}=\frac{0}{-11}=0$

Then, using point-slope form, choose one set of coordinates to use for y1 and x1:

$y-y_{1}=m(x-x_{1})$

$y-(-6)=0(x-4)$

$y+6=0$

$y=-6$

Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.

Jane read 3/8 of a book for 6 days. How many books did she read?

otez555 [7]

$Hey$ $there!$

$The$ $answer$ $to$ $your$ $question$ $is$ $2 \frac{1}{4}$ $books$ .

$To$ $solve$ $this$ , $we$ $must$ $multiply$ $\frac{3}{8}$ $by$ $6$

$\frac{3}{8} *\frac{6}{1}=\frac{18}{8} =2\frac{1}{4}$

$Hope$ $it$ $helps!$ $Have$ $a$ $great$ $day!$

the pressure exerted on the floor by the heel of someone's shoe is inversely proportional to the square of the width of the heel

Katen [24]

P = k/w^2

<span>first of all you need to find k </span>
<span>But I kind of don't like the units of each value so let say </span>
<span>400KPa = 4 * 10^5 Pa = 4 * 10^5 N/m^2 </span>
<span>2 cm = 2 * 10^-2 m </span>

<span>input values in the equation </span>

<span>4*10^5 = k/(4*10^-4) >>> k = 160 N </span>

<span>P = 160/w^2 </span>
<span>it said if she wears a heel with a width of .5 cm </span>

<span>P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa</span>
