A graphed line passes through pair of points. Use the slope formula to find the slope of the line.
(2, 4) and (1, 7)
Question 1 options:
-4
-2
-3
-5
The slope formula is given by:
m = (y₂ - y₁) / (x₂ - x₁)
Let's substitute the values in the formula:
m = (7 - 4) / (1 - 2)
m = 3 / -1
m = -3
Therefore, the slope of the line passing through the points (2, 4) and (1, 7) is -3.
Answer: -3
To find the slope of the line passing through the points (2, 4) and (1, 7), we can use the slope formula, which is:
m = (y2 - y1) / (x2 - x1)
Let's substitute the coordinates into the formula:
m = (7 - 4) / (1 - 2)
Simplifying the equation:
m = 3 / -1
The slope of the line is -3.
Therefore, the correct answer is -3.
To find the slope of a line passing through two given points, you can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Let's label our points as follows:
Point 1: (x1, y1) = (2, 4)
Point 2: (x2, y2) = (1, 7)
Plug these values into the slope formula:
m = (7 - 4) / (1 - 2)
Simplifying the numerator and denominator:
m = 3 / (-1)
The slope of the line passing through the points (2, 4) and (1, 7) is -3.
