What is the slope of the line of the best fit? use points (5,6) and (10,4)

By the looks of it, this would be 2/5 because your x-axis is going by 1, 1.5, 2, 2.5 and so on

Step-by-step explanation:

When finding slope use a thing called rise over run.

You would find your points, in this case (5,6) and (10,4)

If it helps make a dotted triangle from one point to the next point. (refer to my picture)

How many times you count up (rise) from one point, is your numerator

How many times you count across from one point (run) is your denominator

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
