I need some help... Algebra Hw

1. x = 4, y = 1

Graph: (See the attachment)

Step-by-step explanation:

x + 2y = 6

x - y = 3

x + 2y = 6

x = -2y + 6

x - y = 3

-2y + 6 - y = 3

-3y + 6 = 3

-3y = -3

y = 1

x = -2y + 6

x = -2 ( 1 ) + 6

x = 4

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract
