Question

determine the slpoes of the lines padding through these points (3,-1) and (-7,-1)

Answer 1

The slope of a line between two given points P1(x1,y1) and P2(x2,y2) is the increment in y divided by the increment in x.

Increment in y is defined as y2-y1 and increment in x is defined as x2-x1.

So the slope is ...
