#1 first we need to solve for slope which is y2-y1/x2-x1
plug in the coordinates and get 1-6/5-(-2) which makes our slope -5/7
then use the equation for point slope form which is:
y-y1=m(x-x1)
then plug in one of the coordinates, I'll use (-2,6), now we have
y-6=-5/7(x+2)
now to make this slope intercept, we just have to solve
y-6=-5/7x-10/7
y=-5/7x+4 4/7
repeat all these steps for 2 and 3
#2: slope = -13/5
plug it in to point slope and get: y+8=-13/5(x-3)
slope intercept:
y+8= -13/5x + 39/5
y= -13/5x -1/5
#3: slope = 3/4
point slope form: y-2=3/4(x-3)
slope intercept: y-2=3/4x-9/4 --> y=3/4x-1/4

Answer:
Step-by-step explanation:
The formula for exterior angles of a regular polygon is that they must add up to 360. They are also equal for a regular polygon.
Exterior angle = 360 / number of sides
The first one (a pentagon) has 5 sides
Exterior angle = 360/5
Exterior angle = 360/5 = 72
The second one has 8 sides.
Exterior angle = 360/8
Exterior angle = 360/8 = 45
Answer:
Step-by-step explanation:
x² + 3x + 4x + 12 =x(x+3) + 4(x+3)=
