motikmotik

Answer:

x = -5

y = 2

Step-by-step explanation:

x = – 2y – 1

= -x - 2y - 1

-x - 2y = 1

x = – 5y + 5

= -x - 5y + 5

-x - 5y = -5

-x - 2y = 1

-x - 5y = -5

___________--

3y = 6

y = 6/3

<u>y = 2</u>

-x - 2y = 1

-x - 2(2) = 1

-x - 4 = 1

-x = 1 + 4

-x = 5

<u>x = -5</u>

Passes through (4,-1), slope =-3
Yuri [45]
The slope intercept form of this would be y=*3x-1. The formula for slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. I this problem, the y-intercept is -1, so you would plug in -1 for b, so the equation is y=mx-1. The slope is -3, so you plug that in for m, so the equation now becomes y=-3x-1. Hope that helps!!
