A line passes through the point (-1, - 8) and has a slope of -6. Write an equation for this line.In slope intercept form
Alenkasestr [34]

      \rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}

    <em>A line passes through the point (-1, -8) and has a slope of -6. Write an </em>

<em>      equation for the line in slope-intercept form.</em>

<em />

<em />\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}

First, let's write the equation of the line in Point-slope form:-

       \Large\text{$y-y_1=m(x-x_1)$}

Replace y₁ with -8, m with -6, and x₁ with -1:-

          \Large\text{y-(-8)=-6(x-(-1)}

\bigstar On simplification,

         \Large\text{y+8=-6(x+1)}

\bigstar Now let's convert it into slope-intercept form:-

                     \Large\text{y+8=-6x-6}

\bigstar<em> </em>On further simplification,

\Large\text{y=-6x-6-8}

\bigstar Finally, We get

\Large\textit{y=-6x-14}

Find the balance of the account using the simple interest formula of I=Prt
Sever21 [200]

Answer:

$8.75

Step-by-step explanation:

Simple interest can be determined using this formula :

principal x time x interest rate

principal = $1400  

time = 6 months = 6/12 = 0.5

interest rate = 1.25%

$1400 x 0.5 x 0.0125 = $8.75
