The points (-1,r) and (15,1)lie on a line with slope 1/2. Find the missing coordinate r.

maria [59]

Slope is the change in y over the change in x:

Slope = (y2 - y1) / (x2-x1)

Replace the letters in the equation with the given information:

1/2 = (1 - -1) / (15 -r)

Cross multiply:

1 * (15-r) = 2 * (1- -1)

Simplify:

15 -r = 4

Subtract 15 from each side:

-r = -11

Because r is negative, you need to multiply both sides by -1 to make r positive:

r = 11

If two lines are perpendicular, the slope of one of the lines is the negative reciprocal of the other. Since we know the slope for one of our lines, $2$ m lets find the other:
$m=- \frac{1}{2}$

Now, lets use the point-slope formula to complete the equation of our perpendicular line:
$y-y_{1}=m(x-x_{1})$
$y-5=- \frac{1}{2} (x-2)$
$y-5=- \frac{1}{2}x+1$
$y=- \frac{1}{2} x+6$

We can conclude that our perpendicular line is $y=- \frac{1}{2} x+6$
