Move point b to various locations on the circle, and
measure the angles that are formed.
make a conjecture. what relationship exists between the
radius and tangent?
the angles formed by the intersection of the radius
and tangent are right angles.
the angles formed by the intersection of the radius
and tangent measure 90°.
the tangent is perpendicular to the radius.

it is a reproduction.

step-by-step explanation:

slope is 35 and 20 miles is the y-intercept.

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
