Step-by-step explanation:
concept : When two lines are perpendicular, then the product of their slopes is equivalent to -1. Equation of line in the form y = mx + c have m as slope of line and c as y-intercept.
Solution: Given equations 4y = 5x - 10; or, y = (5/4) * x - (5/2); 5y + 4x = 35; ory=(-4/5)x+7. Let m and n be the and ii, respectively
. Here, m = 5/4; n = - 4/5 of lines are .slope of equations
