What is the equation of a line that passes through the point (10, 5) and is perpendicular to the line whose equation is y=5/4x−2 ?

Step-by-step explanation:

5 = −⅘[10] + b

−8

If you want it in Standard Form:

y = −⅘x + 13

+ ⅘x + ⅘x

___________

⅘x + y = 13 [We do not want fractions in our standard equation, so multiply by the denominator to get rid of it.]

5[⅘x + y = 13]

* Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE RATE OF CHANGES [SLOPES], so 1¼ [or 5⁄4] becomes −⅘.
