Answer:
5/2
Explanation:
A line perpendicular what be the reciprocal * -1 of the original line’s slope.
The original line is depicted by the equation 2x + 5y = 10.
By solving for y, the terms are rearranged as -2x/5 + 2 = y. Thus, the slope is -2/5
Like previously stated, the perpendicular line is the reciprocal of the original slope *-1 : -2/5 —> -1(-5/2) = 5/2
