Segment CD is formed by C(-5, 9) and D(7, 5). If line t is the perpendicular bisector of segment CD , write a linear equation for t in slope-intercept form.

Given:

Segment CD is formed by C(-5, 9) and D(7, 5).

Line t is the perpendicular bisector of segment CD.

To find:

The linear equation for t in slope-intercept form.

Solution:

Line t is the perpendicular bisector of segment CD. It means line t passes through the midpoint of CD.

Slope of CD is

Product of slopes of two perpendicular lines is -1.

Let slope of line t be .

Point slope form of a line is

where, m is slope.

The slope of line t is 3 and it passes through (1,7). So, point slope form of line t is

Therefore, the point slope form of line t is .

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
