Question

How do these work? I’m still not good at these.

Answer 1

The first line passes through (5,0) and (0,-5) so the slope is:

`((-5)-0)/(0-5)=1`

So slope of first line is 1.

The second line passes through the points (1,0) and (0,4) so the slope of the line is given by:

`(4-0)/(0-1)=-4`

So slope of the second line is -4.
