I think it's b or d
Step-by-step explanation:
he spends 9.6 hours sleeping each day! plz mark me the brainliest!
Try using the simple interest formula, I=p+r or use rate of change.
Slope intercept form= y=mx+b.
y=9x-9
Slope formula:
(y2-y1)/(x2-x1)
Substitute in the points into the slope formula.
Slope= [10-(-2)] / [(-7)-8]
Slope= (10+2) / (-15)
Slope= 12/-15
Slope= -12/15
Simplify (3 goes into each)
Slope= -4/5
Hope this helps!! :)
