Semester 1 Midterm Exam 2024

Front

Calculate the slope of the line passing through the points (2, 3) and (5, 9)

Back

Slope = (y2 - y1) / (x2 - x1) = (9 - 3) / (5 - 2) = 6 / 3 = 2.

Front

In the equation y=mx+b, what does 'm' represent?

Back

'm' represents the slope of the line.

Front

Solve the inequality 3x + 7 < 22

Back

x < 5.

Front

Is this mapping a function or not a function?

Back

Not a Function.

Front

What is a negative correlation?

Back

A relationship between two variables where one variable increases as the other decreases.

Front

Define slope in the context of a graph.

Back

Slope is a measure of the steepness of a line, calculated as the rise over run.

Front

What is the y-intercept in the equation y=mx+b?

Back

The y-intercept is the value of y when x=0.

Front

How do you determine if a relation is a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value).

Front

What does it mean for a graph to have a positive correlation?

Back

In a positive correlation, as one variable increases, the other variable also increases.

Front

What is the formula for calculating the slope between two points?

Back

Slope = (y2 - y1) / (x2 - x1).
