In a direct variation, if y=39 when x=3, what is the value of y when x=2?

Back

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y over the change in x.

Front

What does it mean for two variables to be correlated?

Back

It means there is a statistical relationship between the two variables, but one does not necessarily cause the other.

Front

Write the equation of a line with a slope of 1 that passes through the point (0, 2).

Back

y = x + 2

Front

What is the formula for direct variation?

Back

y = kx, where k is a constant.

Front

If the slope of a line is negative, what does that indicate about the direction of the line?

Back

The line decreases as it moves from left to right.
