Ill give brainlyest to anyone who can help
stepladder [879]

Answer:

Step-by-step explanation:

Substitution  method:

y= -2x + 2

x - 2y = 6

so y = (-2x + 2)

Substitute into y

Hence x - 2y = 6 is:

x + 2x +2 = 6    (+2x because there was - in the equations so -×- = +)

3x + 2=6

Then bring 2 to the other side so

3x = 6-2

3x = 4

x = 3/4 or 0.75

To find y :

y= (-2 × 3/4) + 2

y = -1.5 +2

y = 0.5

That's all I can do for now!

What is the equation for the line that passes through the points (-2,1) and (1,-11)
givi [52]

Answer:

y=4x+7

Step-by-step

(-2,1) and (1,-11)

1)Rule you should use is run over rise aka slope

y²-y^1=

x^2-x^1=

(-11)-1=12

1-(-2)=3

12/3=4

slope =4

2)Rule of point slope intercept

y - y1 = m(x - x1)

y+1=4(x+2)

y+1=4x+8

   -1     -1

y=4x+7
