Answer:
84
Step-by-step explanation:
Pretend her first 3 quizzes were all 83 since that was the average. So the 4th was 87.
83+83+83+87 = 336
Divide by the total number of quizzes because they are equally weighted.
336/4 = 84
Her new average score is 84.
Answer:
y = -x + 1
Step-by-step explanation:
First, simplify -x+y=-6 to y = x - 6
Being perpendicular, then the x needs to be "flipped", making the slope y = -x
In order to have the slope go through (-4, 5), the line needs to intercept the y-axis at 1
Thus, the equation is
y = -x + 1
