Answer:
6
Step-by-step explanation:
After 10 hours he has graded 10*7 papers which is 70
76-70 = 6
Answer:
y = (-3/5)x - 7
Step-by-step explanation:
you are given the points (5,-10), (-10,-1)
a slope of (-1+10)/(-10-5) = -9/15 = -3/5 can be determined
using the point (0,-7), we can get y+7=(-3/5)(x - 0)
simplified: y = (-3/5)x - 7
0.178 as a fraction is <span>89/<span>500 !</span></span>
Answer: y=-2x+12
Step-by-step explanation:
The slope goes down which makes it negative and the two yellow points make a line with a slope of =2. If you follow the line up, it would cross the y-intersection at 12. So the final line is y=-2x+12
These lines are= parallel
thus no answer.
