At the beginning of the year, Evelyn had $30 in savings and saved an additional $12 each week thereafter. Cooper started the yea

r with $75 and saved $7 every week. Let E E represent the amount of money Evelyn has saved t t weeks after the beginning of the year and let C C represent the amount of money Cooper has saved t t weeks after the beginning of the year. Write an equation for each situation, in terms of t , t, and determine the interval of time when Evelyn has more in savings than Cooper.

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
