What is the equation of the line that passes through the point (-3,1) and has a
slope of 2/3?

y = x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = , thus

y = x + c ← is the partial equation

To find c substitute (- 3, 1) into the partial equation

1 = - 2 + c ⇒ c = 1 + 2 = 3

y = x + 3 ← equation of line

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
