find the slope if it exists of the line containing the pair of points
(-5.5,13.6) and (-5.3, 7.8)
the slope m=?
m=(y2-y1)/(x2-x1)
To find the slope of a line containing two points, you can use the formula:
m = (y2 - y1) / (x2 - x1)
Let's solve the equation using the given points (-5.5,13.6) and (-5.3, 7.8):
x1 = -5.5
y1 = 13.6
x2 = -5.3
y2 = 7.8
Substituting these values into the slope formula:
m = (7.8 - 13.6) / (-5.3 - (-5.5))
m = (7.8 - 13.6) / (-5.3 + 5.5)
m = (-5.8) / (0.2)
Now we can simplify the expression:
m = -5.8 / 0.2
To divide 5.8 by 0.2, we invert the divisor (0.2) and multiply:
m = -5.8 * (1 / 0.2)
m = -5.8 * 5
Finally, we get the answer:
m = -29
Therefore, the slope (m) of the line containing the points (-5.5,13.6) and (-5.3, 7.8) is -29.
