The teacher that corrected the greatest amount would be Mr. James. Reason for this would be that 5/8 is .625 and when you move the decimal to places to the right to make a percent, you would get 62%
Answer:
d
Step-by-step explanation:
The answer is y=2. Hope this helps!
3x+x= total
3x= number of miles driven on saturday
Idk if I did this right but I tried... If I did wrong I can try again but yea idk
Original line: y=1/2x-9
Perpendicular lines have opposite slopes from the original lines. Since the original slope is 1/2, the perpendicular slope will be -2/1 or -2. The numbers switch places and switches from positive to negative.
New line: y=-2x+b
To solve for the y-intercept (b), plug the given coordinates (3,2) into the x and y spots in the equation:
2=-2(3)+b
Now, solve for b.
2=-6+b
Add 6 to both sides.
8=b
The y intercept is 8.
Now, your perpendicular line equation is:
y=-2x+8
I hope this helps :)
