What is the slope of a line that is perpendicular to 4x-8y=64

aleksley [76]

Answer:

- 2

Step-by-step explanation:

1) Write the equation in slope-intercept form.

4x - 8y = 64

-8y = -4x +64

y = 1/2 x - 8

slope of this line = 1/2

2) For perpendicular line the slope is negative reciprocal.

So, slope for perpendicular line is equal -2.
