Question

The equation of the line of best fit of a scatter plot is y = −4x − 6. What is the slope of the equation?

Answer 1

The slope-intercept form of a line is:

y=mx+b, where m=slope and b=y-intecept

So if y=-4x-6 the slope is -4.

Answer 2

Y = -4x -6  

the equation is written in slope intercept form ( y = mx +b ) where b is the y intercept
therefore the y intercept is -6
