Question

Made a mistake with slope.
I have two points on a line, 17.5, 17 and 21, 7. When I followed the slope formula,
m = y2 - y1/ x2 - x1, I got -10/3.5 as my slope. I'm super jittery and really want my corrections to be correct, so could someone confirm that the -10 is allowed in the all-positive quadrant? Is it because the slope is going downward towards the right?

Answer 1

For slope, I got -20/7.

That is the same as what you got >> -10/3.5 if you simplify your answer.

Answer 2

-10/3.5 as a slope means that each time x moves 3.5 units forward, the corresponding y-value drops 10. These are directions and not signed numbers of points in the first quadrant.

With a negative slope, as x increases then y decreases. So, expect the line to fall.
