Answer:

y - 5 = -1(x + 3)

Step-by-step explanation:

Point slope form

y - y1 = m(x - x1) where m = slope and passing through point (x1 , y1)

In this case if the equation in point-slope form contains the point (–3, 5) and has slope –1 then the equation should be:

y - 5 = -1(x - (-3))

y - 5 = -1(x + 3)

The original line has the equation of y=-2x+8
enot [183]

The new equation of line that is perpendicular to the original that goes through the point (6, -1) in slope intercept form is y = \frac{1}{2}x - 4

<h3><u>Solution:</u></h3>

Given that original line has the equation of y = -2x + 8

We have to write a new equation that is perpendicular to the original that goes through the point (6, -1)

Let us first find slope of original line

<em><u>The slope intercept form of line is given as:</u></em>

y = mx + c ------ eqn 1

Where "m" is the slope of line and "c" is the y - intercept

On comparing the slope intercept form and given original equation, we get "m = -2"

Thus slope of original line "m" = -2

We know that product of slope of a line and slope of line perpendicular to it are always -1

slope of original line x slope of line perpendicular to it = -1

\begin{array}{l}{-2 \times \text { slope of line perpendicular to it }=-1} \\\\ {\text { slope of line perpendicular to it }=\frac{1}{2}}\end{array}

Let us find equation of line with slope m = 1/2 and passes through point (6, - 1)

Substitute m = \frac{1}{2} and (x, y) = (6, -1) in eqn 1

-1 = \frac{1}{2} \times 6 + c\\\\-1 = 3 + c\\\\c = -4

<em><u>Thus the required equation of line is:</u></em>

Substitute "c" = -4 and m = \frac{1}{2} in eqn 1

y = \frac{1}{2}x - 4

Thus the equation of line perpendicular to original line is found

Jonah is saving up to purchase a small
wel

Answer:

  $125

Step-by-step explanation:

You can write an equation from the problem statement:

  $80 = 0.64 × (total cost)

This is solved by dividing by 0.64.

  $80/0.64 = $125 = (total cost)

_____

Of course, you know that ...

  64% = 64/100 = 0.64

Both fractions are read as "sixty-four hundredths."
