MATH 1 EOC REVIEW NC Exam 2026
Questions and Answers Graded A+
Average Rate of Change - Correct answer-Means SLOPE.
The "m" in front of x
Change in y divided by change in x
Exponential DECAY graphs - Correct answer-Exponential decay graphs curve
down
Exponential GROWTH graph - Correct answer-Exponential growth graphs curve
up
Midpoint formula - Correct answer-The point in the middle of a line segment
Parallel lines and slope - Correct answer-Have the same or equal slopes
Perpendicular lines & slope - Correct answer-Have opposite reciprocal slopes
(flipped and sign changed) Ex. 3/2--> -2/3
Domain of a relation - Correct answer-Domain: the x coordinates, input values,
independent variables, on x axis
, Range of a relation - Correct answer-Range: the y coordinates, output values,
dependent variable, on the y axis
"adding or subtracting by the same amount" means... - Correct answer-The
equation is an LINEAR function
"multiplying by the same amount" means... - Correct answer-The equation is an
EXPONENTIAL function
No Solution vs. Infinitely Many Solutions (all real #'s) - Correct answer-When
solving if all variables disappear,
"No Solution": when 5=21
"Infinitely Many Solutions": when 5=5
To graph data on calc. - Correct answer-To enter data: STAT, edit, input#s, ENTER
To make scatterplot: turn on Plot 1, graph, ZOOM 9
Normal Distribution - Correct answer-Mound of data in the middle
High in the middle, even on each side
Standard Deviation (what does it mean?) - Correct answer-2/3 of data or 67% of
data is under the mountain
Positively Skewed - Correct answer-Long tail on the right
