Question

The equation of the line of best fit of a scatter plot is y = −4x − 6. What is the the y-intercept? can someone please help?

Answer 1

−6
−9
9
6

Answer 2

Slope-int formula
\(\large y = mx + b\)

y = output (y-coordinate)
m = slope
x = input (x-coordinate)
b = y-intercept (where the line crosses the y-axis)

Answer 3

6

Answer 4

no wait 4

Answer 5

-4

Answer 6

-4 is the slope. see how it is attached to the \(x\)

Answer 7

yes

Answer 8

thanks

Answer 9

the y-int is -6.
take account the subtraction/negative sign in front of the six
\(\large y = -4x \color{red}{-} 6\)
