what is the slope of the line perpendicular to y=2/5x+7

slope of line y=(2/5)x+7

is (2/5)
Slope of line perpendicular to it is
-(1/slope)=-5/2.

To find the slope of the line perpendicular to a given line, we need to consider the relationship between the slopes of perpendicular lines.

The given line is in the form y = mx + b, where m is the slope. So, the slope of the given line is 2/5.

The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope.

In this case, the negative reciprocal of 2/5 is -5/2.

Therefore, the slope of the line perpendicular to y = 2/5x + 7 is -5/2.
