Write the equation of a line that is perpendicular to y = -8 3 x + 4 and goes through the point (5, 2)
zhuklara [117]

Answer:

y = 3/8x + 1/8

Step-by-step explanation:

The slope of a perpendicular line is the opposite and reciprocal of the original slope.

-8/3 -> 3/8

Find the new y-intercept.

y = 3/8x + b

2 = 3/8(5) + b

2 = 1.875 + b

0.125 = b

y = 3/8x + 1/8

Best of Luck!
