What is the slope of the line passing through points a and b?

1/3

Step-by-step explanation:

you go up 1 and down 3

1/3

Step-by-step explanation:

The way to find slop is find the RISE/RUN between the two points.

i think the answer is b

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
