The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains

aniked [119]

Answer:

$y=-2x+13$

Step-by-step explanation:

Equation of the line CD is given as $y=-2x-2$

Slope of the line CD = -2

Slope of the line parallel to CD = -2

Equation of the line parallel to CD is given by $y=mx+c$

$y=-2x+c$

But this line passes through (4,5)

Substituting the values in the equation:

$5=-2*(4)+c$

=> $c=5+8=13$

So the overall equation of the parallel line is given by $y=-2x+13$

The slope-point form of line:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-9, 7) and (6, 2). Substitute:

$m=\dfrac{2-7}{6-(-9)}=\dfrac{-5}{6+9}=-\dfrac{5}{15}=-\dfrac{1}{3}\\\\y-7=-\dfrac{1}{3}(x-(-9))\\\\\boxed{y-7=-\dfrac{1}{3}(x+9)}$

The slope-intercept form of line:

$y=mx+b$ .

We have the slope m:

$y=-\dfrac{1}{3}x+b$

Pu the coordinates of the point (6, 2) to the equation:

$2=-\dfrac{1}{3}(6)+b$

$2=-2+b$ <em>add 2 to both sides</em>

$4=b\to b=4$

$\boxed{y=-\dfrac{1}{3}x+4}$

Jeanne makes hair bows to sell at the craft fair. Each bow requires 1.5 yards of ribbon.At the fabric store, ribbon is sold by

Over [174]

1.5 yards of ribbon per bow
84 bows need to be made, so 1.5 x 84 = 126 yards

1 yard = 0.33 feet, so 126/0.33=381.8181 (ans must round up)

So Jeanne will need 382 feet of ribbon
