Question

Slope of the red line

Answer 1

The red line appears to go through (0, 1.5) and (1,0) so has slope

`m = ( 1.5 - 0)/(0 - 1) = -1.5 = -\frac 3 2`

Choice A.

Answer 2

Because the line is sloping downwards, A is the only one that makes sense because it is the only negative slope.

Slope = y2 - y1 / x2 - x1

take any points it will always be the same;

(0, 1.5) (1,0)

0 - 1.5 / 1 - 0 =

-1.5 / 1 or -1.5 or -3/2
