Question

The equation of the line of best fit of a scatter plot is y = 6x − 9. What is the slope of the equation? –6 –9 9 6

Answer 1

Answer:

D. 6

Step-by-step explanation:

The line of best fit represents the relation between two variables, usually indicated as x and y, where "x" is the independent variable and "y" is the dependent variable.

The general form of equation of the line of fit y = mx + b, where "m" represents the slope and b represents the y-intercept.

The given line of best fit of a scatter plot is y = 6x - 9

Now compare the given equation with the general and find the slope.

When we comparing, we get m = 6 which is the slope of the given equation.

Therefore, answer is D. 6

Answer 2

6 is the answer because it is 6x therefore the gradient increases by 6 each time<span />
