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

I think it is -6 but im not sure

Answer 2

HI!!

Answer 3

the slope is the number in front of the x
what is that number?

Answer 4

or let me ask it another way
where do you see a minus sign?

Answer 5

The equation of a line is y=mx+b where m is the slope.

Answer 6

so its -9 ?

Answer 7

@misty1212 ?

Answer 8

\[\huge y=mx+b ~~~ m = slope\]

Answer 9

Now compare the equation with yours

Answer 10

m = 6 ?

Answer 11

Yes :)

Answer 12

thanks

Answer 13

\[ y = \color{red}mx+b\\
y = \color{red}6x − 9\]
