Question

Find the slope of the line passing through the points (8,-4) and (-7, -4).

Answer 1

Hi!

I can help you with joy!

• If you notice, the y-coordinates of the points are the same.
• This means the slope of the line is 0, because its rise is 0.
• Let's use the slope formula:
• 
  `\displaystyle(y2-y1)/(x2-x1) \\\displaystyle(-4-(-4))/(7-8)`
• Simplify:
• 
  `\displaystyle(-4+4)/(-7-8)`
• Simplify:
• 
  `\displaystyle(0)/(1)`

Answer:

The slope of the line is 0.

Hope it helps.

Answer 2

Explanation:

slope=m=(Y2-Y1)/(X2-X1)

As given values

take, (X1,Y1)=(-7,-4)

(X2-Y2)=(8,8)

hence X1=-7 , Y1= -4 , X2=8 , Y2= 8

putt the values in the above equation of slope we get ,

m=(8-(-4))/(8-(-7)

m=12/15 Ans
