Slope = (y2 - y1)/(x2 - x1) = (1 - 3)/(-2 - (-5)) = -2/(-2 + 5) = -2/3
For perpendicular lines, m2 = -1/m1 = -1/(3/8) = -8/3
A line passing through point (-4, 0) and parallel to the y-axis is x = -4

radius = diameter/2 = 10/2 = 5
center of circle = midpoint of diameter = ((-3 + 5)/2, (1 + 7)/2) = (2/2, 8/2) = (1, 4)
Required equation is (x - 1)^2 + (y - 4)^2 = 5^2
(x - 1)^2 + (y - 4)^2 = 25
If you’re trying to find the value of x it is -5
Answer:
Line 1: -2
Line 2: 2
Line 3: 2
Line 1 & 2 is parallel.
Line 2 & 3 is neither.
Step-by-step explanation:
To find the slope of a line use the slope formula and substitute the points into it:
Line 1

Line 2

Line 3

Parallel lines have the same slope and perpendicular lines have negative reciprocal slopes.
Line 1 & 2 is parallel.
Line 2 & 3 is neither.
Answer: 47 17/18
Step-by-step explanation:
48 + 1/9 (-1/2)
48 - 1/18 = 47 17/18
