Answer:
4
Step-by-step explanation:
to find the slope from 2 points, you do y2-y1/x2-x1
in this case, it would be -57-(-69)=12
and then x2-x1 is 17-14=3
so, the slope is 12/3 or 4
Answer:
(-1,-4)
Step-by-step explanation:
Because it is a rotation that turns both the x and y values the two swap places. The x value become negative because before it was in quadrant 4 where there was still a positive chance but rotating the point clockwise puts it into the third quadrant where there are only negatives.
Answer:
35 questions
Step-by-step explanation:
First find out how many questions he got right setting up an equation.
1)3x=84.
The variable 'x' is the answers he got correct. The next step would be to divide by 3 to get the x alone. Remember, whatever you do to one side is done to the other so divide 84 by three as well
2) 3x÷3 = x.
84÷3=28.
which leads you to x=28.
Then, since he got 7 wrong, you would add the 7 to the 28 he got correct to get the final answer.
3) 28+7=35
another way you can do this is multiply numbers by three until you get to 84. The number you multiplied by is the amount he got correct, then add the correct and wrong ones together to get 35
