Percent increase = (new number - original number) / original number...* 100
= (2075 - 1195) / (1195)...* 100
= (880 / 1195) * 100
= 0.736 * 100
= 73.6 rounds to 74% <==

Tanya’s rotation maps point K(24, –15) to K’(–15, –24). Which describes the rotation?

90 degree rotation clockwise : (a,b) --> (b,-a)
so... (24,-15) --> (-15,-24) is a 90 degree clockwise rotation

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

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