~~! multiple choice ! ~~

a line has a slope of -3 and passes through the point (4,-3)

which is the equation of the line?
a) y= -3x-15
b) y= -3x-9
c) y= -3x+9
d) y= -3x+15

Equation of straight line in slope form = 》( y-y1) = m (x - x1)

Thus here solving ....

y +3 = -3 (x-4)

=》 y+3= -3x +12

=》 y = -3x +9

option c.) y = -3x +9

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
