Trend lines Q2 review

Front

What is the slope in the equation: y=mx+b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

In the equation y=4x+3, what does the number 4 represent?

Back

The number 4 represents the slope of the line.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

Front

If m=3 and b=6, what is the slope-intercept equation?

Back

y=3x+6.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables using dots.

Front

What does a positive correlation in a scatter plot look like?

Back

A positive correlation shows that as one variable increases, the other variable also increases.

Front

What does a negative correlation in a scatter plot look like?

Back

A negative correlation shows that as one variable increases, the other variable decreases.

Front

What is the y-intercept in the equation y=4x+3?

Back

The y-intercept is 3, which is the value of y when x=0.
