I Need Help Figuring This Question Out Any Thoughts class=

Sagot :

Answer: y= -1/2 + 6
How: rise over run

Answer:

[tex]y=-\frac{5}{9}x+6[/tex]

Step-by-step explanation:

Do what the question says and use the two orange points to figure out the slope of the line. We see that the orange parts are [tex](x_1,y_1)\rightarrow(0,6)[/tex] and [tex](x_2,y_2)\rightarrow(9,1)[/tex].

[tex]Slope=m=\frac{y_2-y_1}{x_2-x_1}=\frac{1-6}{9-0}=\frac{-5}{9}=-\frac{5}{9}[/tex]

Since [tex](0,6)[/tex] is a point on the line of best fit, this means our y-intercept is b=6, making the final equation [tex]y=-\frac{5}{9}x+6[/tex]
