Area = S^2

S(S-3) =70

S^2 -3S = 70
S^2 - 3s-70 = 0

(s-10) (s+7) = 0

s = 10, s=-7

S=10

original dimension was 10cm x 10cm

What is the standard form equation of the line shown below?

Fantom [35]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

The formula of a slope:

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

We have the points (-2, 3) and (1, -3). Substitute:

$m=\dfrac{-3-3}{1-(-2)}=\dfrac{-6}{3}=-2\\\\y-(-3)=-2(x-1)\\\\y+3=-2(x-1)$

The standard form: Ax + By = C. Convert:

$y+3=-2(x-1)$ use distributive property

$y+3=-2x+2$ subtract 3 from both sides

$y=-2x-1$ add 2x to both sides

$\boxed{2x+y=-1}\to\boxed{c.}$
