Question

What is the slope of the line passing through the following points: #(-3, 1) , (4, -1) #?

Answer 1

The formula for slope is m = `(y_2 - y_1)/(x_2 - x_1)`, where m represents slope.

Explanation:

m = `(y_2 - y_1)/(x_2 - x_1)`

m = `(-1 - 1)/(4- (-3))`

m = `-2/7`

Your slope is `-2/7`.

Exercises:

1. Find the slope of the following line segment: graph{y = -1/2x + 3 [-10, 10, -5, 5]}

2. Find the slope of the line passing through the following points:

a) (2, -8) and (-3,4)

b) (-3,-5) and (6, 2)

1. Find the slopes of the following lines:

a) y - 2 = 3(x + 5)

b) y = 3x + 6

c) 5x - 3y = -8

Good luck!
