Subtract second y from first y and divide that by second x from first x
1-2=-1
3- -5=3+5= 8
so, -1/8
this is your m= -1/8
now pick one of the points and add it to your point intercept form (I'm picking (3,1))
y-1= -1/8 (x-3)
y-1= -1/8x - (-1/8×3)
y-1= -1/8x +3/8
y= -1/8x +3/8+1
y= -1/8x +11/8
Where the full question at?
Hey there!
The equation for finding the sum of the interior angles for a polygon with n sides is the following:
"Hepta-" means seven; thus, a heptagon has 7 sides.
Since a heptagon has 7 sides, n=7.
Now, let's plug in that value into the equation.
Thus, the sum of all interior angles in a heptagon is 900 degrees.
Have an awesome day! :)

Answer: Choice C) Undefined slope is when there is no vertical change
If you replace "vertical" with "horizontal", then choice C would be a true statement. All vertical lines have an undefined slope.
This is because the slope formula
m = (y2-y1)/(x2-x1)
has 0 in the denominator when you subtract the x coordinates. Dividing by zero is undefined. For any single vertical line, the x coordinates of any two points are the same. For instance, the vertical line through 4 on the x axis is the equation x = 4, and every point on this line has x coordinate 4.
