Domain and range of 7-9 / 2-7 and what does the slope of the equation mean

Domain: 7,2

Range: 9,7

Slope is 2/5

Step-by-step explanation:

Domain is basically the x coordinates, which are 7 and 2 in this case. Range is the y coordinates: 9 and 7.

The slope is basically the line that connects these two dots.

Slope formula is (y2-y1)/(x2-x1)

But the points of the grid would be listed as (x1,y1) (x2,y2)

I don't know if I'm explaining this well enough, but if you follow that formula you get (7-9)/(2-7).

That equals to 2/5.

I hope this helped
