Could be italic or possibly copperplate.
Well, when the slopes of the perpendicular sides of the right triangle are mutiplied, the result should be -1.
Italian
Positve slopes increase on the chart and negative decreases. Positive increase from 0 to the top right corner of the chart.
a verticla line
If two lines in the same plane intersect to form a right angle, then their slopes are negative reciprocals. Representing their slopes by sa and sb, then sa = -1/sb .

why demand curve slopes downward from left to the right
A line that slopes to the right and up has a positive slope.

This has a negative slope (it slopes 'down' as you move from left to right).
i wanna ask too lol
slopes downward
indifference curves slopes downward to the right
