How do you find the slope of (8, 4) and (9, 7)?

Answer 1

Isaiah Anthony

See a solution process below:

The formula for find the slope of a line is:

#m = (color(red)(y_2) - color(blue)(y_1))/(color(red)(x_2) - color(blue)(x_1))#

Where #(color(blue)(x_1), color(blue)(y_1))# and #(color(red)(x_2), color(red)(y_2))# are two points on the line.

Substituting the values from the points in the problem gives:

#m = (color(red)(7) - color(blue)(4))/(color(red)(9) - color(blue)(8)) = 3/1 = 3#

To find the slope of a line passing through two points, you can use the formula:

Slope (m) = (change in y) / (change in x)

Given the points (8, 4) and (9, 7), you can calculate the change in y (Δy) and the change in x (Δx) as follows:

Δy = 7 - 4 = 3 Δx = 9 - 8 = 1

Now, plug these values into the formula:

Slope (m) = Δy / Δx = 3 / 1 = 3

Therefore, the slope of the line passing through the points (8, 4) and (9, 7) is 3.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
