BECAUSE IF YOU ROUND THE TENTHS 4 MEANS 0.
Number of earthquakes decreased
Answer:
Neither
Step-by-step explanation:
First, you need to put your equations in y=mx+b form
Your first equation...
5x + 4y = 3
4y = 3-5x
y = -5/4x + 3/4
Your second equation...
5x-4y = -3
-4y = -5x -3
y = 5/4x + 3/4
The slopes aren't the same and are not reciprocals, so the answer would be neither.
Get y by itself so subtract 2x from both sides. So next it would be -4y=-2x+2. To get y by itself divide both sides by -4. So then it would be y= -2/-4x +2/-4. They both reduce down to y=1/2x-1/2. So the slope is 1/2 because the formula y=mx+b
m=slope. Hope this helps! :)
Answer:slope =7/10
Step-by-step explanation:
slope=(y-y0) ➗ (x-x0)
Slope=(8-1) ➗ (4-(-6))
Slope=7 ➗ (4+6)
Slope=7 ➗ 10
Slope=7/10
