He didn’t multiply the equation by 1/2 in the second part so it threw his whole answer off. Hope this helps

The correct answer is the first option.

If you want to use elimination, you can sum the two equations for example, so that the x's simplify:

$(-2x+4y)+(2x+2y) = 16+8$

$6y = 24$

$y = 4$

Plug this value for y in one of the equations to derive the value of x:

$2x+2y=8 \implies 2x + 8 = 8 \implies x = 0$

So, the solution is $(x,y) = (0,4)$

Slope for (x₁, y₁) and (x₂, y₂): (-3, 0) and (2, 7)

Slope: (y₂ -y₁) / (x₂ -x₁)

Slope: ( 7 - 0) / (2 - -3) = 7/(2 + 3)

<span>Slope = 7/5
