Question

Find the slope of a line passing through points (3,4) and (7,10)​

Answer 1

slope of a line passing through points (3,4) and (7,10)

$m = \frac{y2 - y1}{x2 - x1} \\ \\ m = \frac{10 - 4}{7 - 3} \\ m = \frac{6}{4} = 1.5$

Answer 2

Answer:

7/-5 = -7/5

Step-by-step explanation:

From the above question,

The slope of a line is a fraction, where the numerator describes the vertical movement and the denominator describes the horizontal movement. Right and up are positive and left or down are negative. To find the vertical movement, choose one point as point 1, and the other as point 2. For this example, I'll use (3, -4) as point 1.

We can find the vertical movement by subtracting the y coordinate of point 1 from the y coordinate of point 2. In this case, that would be 10 - (-4), which is 10 + 4 or 14. This will be the numerator of the slope.

We can find the horizontal movement by subtracting the x coordinate of point 1 from the x coordinate of point 2. In this case, that would be -7 - 3, which is -10. This will be the denominator of the slope.

With a 14 in the numerator and -10 in the denominator, our slope fraction is 14/-10, which reduces to 7/-5. The negative sign in the denominator could stay there, or it could be moved to the numerator, like this: -7/5.

7/-5 = -7/5
