Answer:

Step-by-step explanation:

use Tangent-chord formula for finding the arc knowing E

x=1/2n

4x+19=1/2n

n=8x+38

both arcs = 360

28x-2+8x+38=360

x=9

If (-2,4) are the coordinates of a point on the line whose equation is y=Mx+1 , what is the slope of the line?

horrorfan [7]

Slope of the line is -3/2

Step-by-step explanation:

Step 1: Given that (-2, 4) is a point on the line y = mx + 1, find slope m.

Since the point is on the line, the coordinates will satisfy the equation.

⇒ 4 = m × -2 + 1

⇒ 4 = -2m + 1

⇒ 3 = -2m

∴ m = -3/2

What is the slope of the line that contains the point (-1,8) and (5,-4) answer.com?

pshichka [43]

THE SLOPE IS -2

if we have the coordinates of two points on a line, we can find the slope with this formula:
$s = \frac{y2 - y1}{x2 -x1} = \frac{y1 - y2}{x1 - x2}$
so the slope is
$\frac{8 - ( - 4)}{ - 1 - 5} = \frac{12}{ - 6} = - 2$
the answer is -2
