Multiply 3x +y =23 by -4

x+4y=4
-12x+(-4y)=-92

Add together

-11x = -88

x = 8

Plug x in to find y.

8 + 4y = 4

Subtract 8 from each sides

4y = -4

Divide by 4

y = -1

So the answer is x =8, y= -1

I hope that helps!

What is the slope of the line passing through the points (−3, 4) and (4, −1)?

Igoryamba

Note:
The slope of a straight line passing through the points (x₁, y₁) and (x₂, y₂) is
$m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

The two given points are (-3,4) and (4,-1). Therefore the slope is
$m= \frac{-1-4}{4-(-3)} = \frac{-5}{7}$

Answer: $- \frac{5}{7}$
