Hey there!!

Steps to get into equation which is perpendicular:

  • Change the slope
  1. The slope of a perpendicular line is always negative reciprocal.
  • Take the point and get that into point-slope form.
  1. y - y = m ( x - x )
  • Convert this equation into slope-intercept form.

'm' is the slope.

We have the slope as 1/3

The perpendicular slope would be -3.

Point slope:

The point = (-2,2)

y - 2 = -3( x - (-2) )

y - 2 = -3(x+2)

y - 2 = -3x -6

Adding 2 on both sides:

y = -3x - 4

<em>Hence, the equation would be : </em>

<u><em>y = -3x - 4 </em></u>

Hope it helps!

Based on the graph, what is the initial value of the linear relationship?
Fofino [41]

The initial value of the linear relationship is 5.

Solution:

  • The y-intercept is the point where the line crosses at y-axis.
  • The initial value of the linear function is the y-intercept.

On observing the graph, the line crosses y-axis at the point (0, 5).

So, y-intercept = 5

That is initial value = 5

Therefore the initial value of the linear relationship is 5.

What is the y-coordinate of point W?<br><br> PLS ASAP
sweet [91]
<h3>Answer:  -1.5</h3>

============================================================

Explanation:

Draw a horizontal line from W to the y axis. You should arrive somewhere between -1 and -2. While this isn't exact, it looks like we should arrive right at the middle of -1 and -2; therefore we should get to -1.5

The y coordinate of W is -1.5

Keep in mind this is based on the assumption we reach the halfway point. Unfortunately, W is not on any horizontal grid lines to be able to determine exactly where W is along the y axis.

Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation. Y=4.5 when x = 3
Nookie1986 [14]
\bf \qquad \qquad \textit{inverse proportional variation}\\\\&#10;\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby &#10;\begin{array}{llll}&#10;k=constant\ of\\&#10;\qquad  variation&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;y=4.5\\&#10;x=3&#10;\end{cases}\implies 4.5=\cfrac{k}{3}\implies 4.5(3)=k&#10;\\\\\\&#10;13.5=k\qquad therefore\qquad \boxed{y=\cfrac{13.5}{x}}
