Answer:
Slope is y2-y1/x2-x1
Let’s make x1 and y1 (6,8)
Let’s make x2 and y2 (2,1)
1-8/2-6
-7/-4
Both are negative numbers, which cancel each other out, making the fraction a positive number.
7/4
A. Would be your answer
Hope I helped!
A. 7/4
Step-by-step explanation:
To find the slope when we have 2 points, we use the formula
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are the given points
m = (1-8)/(2-6)
= -7/-4
=7/4
m = y₂ - y₁/ x₂-x₁
= 1 - 1 / -6-6 = o
Slope = 0
Line will be parallel to x- axis
the 2 parallel lines mean that the lines are equal
SO since BD = 18, DC is also 18
