Solve the following system of equations, using the elimination method:
x + 6y = 79
x - 4y = - 41

Move the center x to the left in order for x to eliminate. Then, move 4y to the left resulting the equation to become 6y + 4y = -41;
10y = -41;
Then, divide both sides with the value of 10 in order to get the value of y. 10/10y = -41/10;
y= -4.1

Using the slope formula m = y2 – y1 x2 – x1 find the slope of the line determined by this pair of points: (-1, 3) and (-6, -4) Here are the multiple choices: 7/5, 2/9, -4/3, 1. There is no graph or picture for this equation, they just have y2 – y1 with a line going through it over x2 – x1 Here are some examples: (-3,-1) and (-9,-6) m=(-1-(-6))/-3-(-9) The Y's on top; X's in denominator. =5/6 . y-(-1)=5/6 (x-(-3)) Point-slope form y+1=5/6 (x+3) y+1=5x/6 + 15/6 y=5x/6 + 9/6 y=5x/6 + 3/2 Slope ...

Solve this proportion: x - 2 = x + 4 4 3 Here are the multiple choices: {- 22} { -11} {0} {7}
To help you understand the equation better it says x-2 over 4 = x +4 over 3

Weegy: The simplified form for the proportion: (x - 2)/4 =( x + 4)/ 3 is {- 22}. (More)

-4 is the answer for x + 1 over 6 and x + 2 over 4.

(x+1)/6=(x+2)/4

(x+1)/3=(x+2)/2

2*(x+1)/3=x+2

2x+2=3(x+2)

2x+2=3x+6

3x-2x=2-6

x=-4.

(x+1)/6=(x+2)/4

(x+1)/3=(x+2)/2

2*(x+1)/3=x+2

2x+2=3(x+2)

2x+2=3x+6

3x-2x=2-6

x=-4.
