A coat regularly cost $125 is put on sale for $75

Stels [109]

If a coat is regularly $125, and they mark it down to $75, we could figure out how much money was taken off by subtracting $75, from $125

$125 - $75 = $50

So the coats price was cut by $50.

Hope it helps

Find an equation for these points (-5,5) (4,2)

user100 [1]

Answer:

$\large\boxed{y=-\dfrac{1}{3}x+\dfrac{10}{3}}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (-5, 5) and (4, 2).

substitute:

$m=\dfrac{2-5}{4-(-5)}=\dfrac{-3}{9}=-\dfrac{1}{3}$

Put the value os a slope and coordinates of the point (4, 2) to the equation of a line:

$2=-\dfrac{1}{3}(4)+b$

$2=-\dfrac{4}{3}+b$ <em>add 4/3 to both sides</em>

$2\dfrac{4}{3}=b\to b=3\dfrac{1}{3}\to b=\dfrac{10}{3}$
