Respuesta :
its just a matter of subbing in ur answer choices to see which ones are correct...but remember, for it to be a solution, it has to satisfy BOTH equations.
(-1/4,-4)
y = 8x - 2
-4 = 8(-1/4) - 2
-4 = - 8/4 - 2
-4 = -2-2
-4 = -4 (correct)
(-1/4,-4)
y = -4x - 5
-4 = -4(-1/4) - 5
-4 = 1 - 4
-4 = -4 (correct)
Therefore, ur solution is (-1/4,-4)
(-1/4,-4)
y = 8x - 2
-4 = 8(-1/4) - 2
-4 = - 8/4 - 2
-4 = -2-2
-4 = -4 (correct)
(-1/4,-4)
y = -4x - 5
-4 = -4(-1/4) - 5
-4 = 1 - 4
-4 = -4 (correct)
Therefore, ur solution is (-1/4,-4)
Answer with explanation:
The two linear equation which are in two variables are
y = 8 x -2---------(1)
y = -4 x -5----------(2)
Equating ,(1) and (2)
→ 8 x -2 = -4 x -5
→8 x + 4 x= 2 -5
→12 x = -3
[tex]x=\frac{-3}{12}\\\\x=\frac{-1}{4}[/tex]
Substituting the value of , x in equation 1
[tex]y=8 \times \frac{-1}{4} -2\\\\y=-2-2\\\\y=-4[/tex]
So, the point of intersection of two lines are
[tex](\frac{-1}{4}, -4)[/tex]
