Answer:
Step-by-step explanation:
Answer: 2/3 is the slope I think and for the same slope thing here is my answer:
We can use similarly of triangles in this case there will be a formation of 2 pairs equal ( angles formed by the y-axis on the parallel lines) angles between triangles formed as the y-axis lines are parallel. So,the slope is the same for both.
Answer: y = -1/3x + 10
Step-by-step explanation:
To make it perpendicular change the reciprocals
So instead of 3x it'll be -1/3x and so it passes through the given points
plug the points
8 = -1/3(6) + b
8 = -2 + b
add 2 to both sides
10 = b
so the equation of a line thats perpendicular to y=-3x-10 and passes through
points (6,8) is
y = -1/3x + 10
The midpoint of the coordinate passing through (2, 4) and (2, -7) is 
<h3>The midpoint of a line</h3>
The formula for calculating the midpoint of a line is expressed as:

Given the coordinate points (2, 4) and (2, -7). Substituting this values

Hence the midpoint of the coordinate passing through (2, 4) and (2, -7) is
