6. What is an equation of the line that passes through the point (2, 4) and is perpendicular to
the line whose equation is y = 2x + 1?

Using the slope-intercept form, the slope is 2 2 .

Step-by-step explanation:

The equation of a perpendicular line to y=2x+4 y = 2 x + 4 must have a slope that is the negative reciprocal of the original slope.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
