Question

Trey believes there is a correlation between the number of texts sent in class and gpa. he collected data and found that the line of best fit for the data can be modeled by the equation y = 4.0 − 0.5x. identify the slope and the type of association. the slope is −4.0, which indicates a negative correlation. the slope is −0.5, which indicates a negative correlation. the slope is 4.0, which indicates a positive correlation. the slope is 0.5, which indicates a positive correlation.

Answer 1

The slope is -0.5, which indicates a negative correlation.

Step-by-step explanation:

y = mx + b

Is a slope-intercept form of the equation.

The y represents the distance of the line from the y-axis. (if u were to graph the problem)

M represents the slope of the line.

An the value of b is equal to y when x = 0

The equation that was given is y = 4.0 - 0.5x, which wasn't written the normal way, like y = mx + b, they just switched the spots from y = mx + b, to y = b + mx.

So the slope is the 0.5. (which is also -0.5)

Trust me, I took a test and it had this answer, and I got it right.

Answer 2

B- -0.5

Explanation:

-.05 is a negative correlation

Negative Correlation definition- Is a situation or an event where two variables move in the opposite direction

(Plus I also Took the test and got it right)
