Answer:

y = -x +3

Step-by-step explanation:

Think about the Y= mx + b

m = -1 so it's -x

b = 3, so it's +3

y intercept goes after the slope:

Y= Mx + B

Y = -x + 3

Determine the area of the composite figure.

MaRussiya [10]

Answer:

$110\ in^2$

Step-by-step explanation:

$1)\ A_1 = b * h_1 = 10 * 8 = 80\ in^2$

$2)\ A_2 = \frac{b*h_2}{2} = \frac{10*(14-8)}{2} = \frac{10*6}{2} = \frac{60}{2} = 30\ in^2$

$3)\ A = A_1 + A_2 = 80 + 30\ in^2 = 110\ in^2$

Lena [83]

Answer:

y=2x-1

Step-by-step explanation:

straight line equation

y=mx + c

find gradient(m) first,use formula;

m=3-7/2-4

m= -4/-2

m=2

use one the coordinates

(2,3)

3=2(2)+c

3=4+c

c=3-4

c = -1

y = 2x - 1
